It is one of the best-rated erasers at US office stores. Staples' 3-pack listing shows 4.84 stars from 1,187 customer reviews, and AsinSight's June 2026 Amazon eraser report placed a Hi-Polymer listing third, behind a Staedtler pack and the Tombow MONO Zero. ## Pentel Hi-Polymer ZEH10 specs | Spec | Value | |---|---| | Maker | Pentel (ASTRUM Corporation, Tokyo) | | Model | ZEH10; 3-pack ZEH10BP3K6; box of 10 ZEH10PC10 | | Size | 65 × 24.5 × 12.5 mm (2.6 × 1 × 0.5 in) | | Color | White, in a blue and black sleeve | | Free of | Latex (AP certified nontoxic) | | For | Pencil on paper | | UPC | Single 072512027660 · 3-pack 072512045206 | | Price band | $ (under $5 per eraser) | | Made in | Taiwan (Pentel of America) | The codes, UPCs and origin are from Pentel of America; the size is from Swiss Post and Cromwell, and US distributors give the same in inches.

Pentel's Japanese product page lists the Ain eraser for light erasing in small (ZEAH06) and large (ZEAH10) sizes, at ¥77 (about US$0.50) and ¥132 (about US$0.80) including tax, plus black versions and multipacks. The Ain is a different product from the ZEH10, so its codes, size and origin don't carry over to the Hi-Polymer. ## Is the ZEH10 large or medium? **Pentel of America calls the ZEH10 large: it sits between the small ZEH05 and the extra-large ZEH20, with a super extra-large ZEH99 above that.** Walmart and a Singapore retailer also say large, while PartsSource and Cromwell say "medium" for the same 65 mm block, so go by the code. Pentel of America also sells a pink ZEH10. The pack codes add letters to the same base: BP3 for a blister of three and PC10 for a box of ten. ## What is it made of? **Pentel calls it a "Hi-Polymer" eraser; one US distributor lists the 3-pack's material as PVC.** That puts it in the same vinyl family as most white block erasers. Pentel of America describes it as non-abrasive and latex-free and says it won't crack or harden with age, a maker claim we haven't tested. Walmart says it is AP certified nontoxic. ## How does it compare with the Staedtler Mars plastic? **They're near twins: the same 65 mm length, with the Hi-Polymer slightly wider and thinner.** | | Pentel Hi-Polymer ZEH10 | [Staedtler Mars plastic 526 50](https://stationerytimes.com/guides/staedtler-mars-plastic-eraser/) | |---|---|---| | Size | 65 × 24.5 × 12.5 mm | 65 × 23 × 13 mm | | Sleeve | Blue and black paper | Blue | | Latex-free | Yes (per retailers) | Yes (per retailers) | | Made in | Taiwan (Pentel of America) | Germany (per retailers) | | Price band | $ (under $5) | $ (under $5) | Both suit graphite on paper. For a single letter, a pen-style eraser such as the [Tombow MONO Zero](https://stationerytimes.com/guides/tombow-mono-zero-eraser/) is more precise. ## How do you get the cleanest erase? **Press lightly and let the eraser do the work.** Pentel of America says it removes lead cleanly with very little pressure, and pressing hard on thin paper is what scuffs the surface and leaves a shiny patch. Rub in one direction, brush the crumbs off rather than wiping them across the page, and wipe a dirty eraser on scrap paper first. A grey eraser face carries graphite back onto the sheet. ## Which pencils is it good with? **Any graphite pencil, from school #2 to soft drawing grades.** For everyday writing it pairs with a [Ticonderoga #2](https://stationerytimes.com/guides/ticonderoga-2-pencil/) or a [Pentel Sharp P205](https://stationerytimes.com/guides/pentel-sharp-p205/); soft grades leave more graphite to lift. Use a clean corner for small areas. Pentel says to keep it in the sleeve, which also keeps the eraser from picking up dirt that would smear. ## Where is the Pentel Hi-Polymer made? **In Taiwan: Pentel of America's 2023–2024 product guide gives Taiwan as the origin of its Hi-Polymer block erasers (the eraser caps are made in China).** PartsSource and On Time Supplies list Taiwan for the single, the 3-pack and the box of 10. Pentel is a Japanese brand; since April 1, 2026, the company behind it is called ASTRUM Corporation. Pentel's Japanese site doesn't list the ZEH10 at all. ## Frequently asked questions ### How big is the Pentel Hi-Polymer eraser? The ZEH10 is listed at 65 × 24.5 × 12.5 mm, about 2.6 × 1 × 0.5 in. A Singapore retailer gives 66 × 20 × 13 mm, so expect small differences between listings. ### Is the Pentel Hi-Polymer eraser latex-free? Yes. US listings describe it as latex-free and AP certified nontoxic, and a Staples reviewer with a latex allergy reported using it. ### Is the ZEH10 large or medium? Large, according to Pentel of America, which sells the ZEH10 as its large block between the small ZEH05 and the extra-large ZEH20. PartsSource and Cromwell call it medium, so go by the code. ### What is the sleeve on a Hi-Polymer eraser for? Pentel of America says block erasers should be used and stored in their protective sleeve. It keeps the eraser clean in a bag or case, and you slide it back as the eraser wears. ### Is the Pentel Hi-Polymer better than the Staedtler Mars plastic? They're close: both are white vinyl-type block erasers of the same 65 mm length. The Hi-Polymer is 1.5 mm wider and 0.5 mm thinner; we haven't tested them side by side yet. ### Does the Hi-Polymer eraser get hard over time? Pentel of America says it won't crack or harden with age. That's a maker claim; keeping it in the sleeve away from heat and plastic pencil cases helps any eraser last. ### Where is the Pentel Hi-Polymer eraser made? In Taiwan, according to Pentel of America's product guide. Pentel itself is based in Tokyo, Japan. ## Sources - [Pentel Ain 消しゴム (Pentel Japan product page: Ain erasers ZEAH06 and ZEAH10, ¥77 and ¥132; no ZEH10 listed)](https://www.pentel.co.jp/products/correctionproducts/ain_eraser/) - [Pentel of America: Hi-Polymer Eraser, Large (ZEH-10, UPC, sleeve, won't harden)](https://www.pentel.com/products/hi-polymer-eraser-large) - [Pentel of America: Hi-Polymer Block Eraser Large White, 3 Pack (ZEH10BP3-K6, UPC)](https://www.pentel.com/products/hi-polymer-block-eraser-large-white-3-pack) - [Pentel of America: 2023–2024 product guide, erasers (Hi-Polymer block sizes, origin Taiwan)](https://pentel.mywestamerica.com/2023ProductGuide/77/) - [Swiss Post shop: Pentel Hi-Polymer ZEH10ST eraser, white, 65 × 24.5 × 12.5 mm](https://shop.post.ch/en/stationery/writing-utensils/correctors/pentel-radierer-hi-polymer-zeh10st-weiss-65x24-5x12-5mm/p/802280) - [Cromwell: Pentel ZEH10 eraser (medium, 65 × 24.5 × 12.5 mm)](https://cromwell.co.uk/shop/irodaszerek/erasers/zeh10-eraser/p/PNL8461140K) - [Stationery World: Pentel Hi-Polymer large eraser ZEH10 (6.6 × 2.0 × 1.3 cm)](https://stationeryworld.com.sg/pentel-hi-polymer-large-eraser-zeh10) - [PF Star: ZEH10 Pentel Hi-Polymer eraser, white block, 2.6 inches](https://pfstar.com/ZEH10-Pentel-Hi-Polymer-Eraser-White-Block-2.6-inches) - [On Time Supplies: Pentel ZEH10 Hi-Polymer eraser (2.6 × 0.5 × 1 in, UPC, country TW)](https://www.ontimesupplies.com/penzeh10-hi-polymer-eraser-white-block-26-width-x-05-height-x-1-depth-x-1-each-non-abrasive-latex-free.html) - [PartsSource: Pentel of America ZEH10 (country of origin Taiwan)](https://partssource.com/parts/pentel-of-america/ZEH10) - [Aztec: Pentel Hi-Polymer eraser 3-pack ZEH10BP3K6 (UPC 072512045206, PVC)](https://www.aztekc.com/eraserhi-polymer3-pk-pentel-of-america/p) - [Walmart: Pentel Hi-Polymer eraser, large, nonabrasive, white (ZEH10)](https://www.walmart.com/ip/22846993) - [Staples: Pentel Hi-Polymer eraser, white (ZEH10)](https://www.staples.com/pentel-hi-polymer-eraser-white-zeh10/product_500512) - [Staples: customer reviews, Pentel Hi-Polymer latex-free block eraser, 3-pack (ZEH10BP3)](https://www.staples.com/ptd/review/253203) - [UBC Bookstore: Pentel white Hi-Polymer eraser, large](https://the.bookstore.ubc.ca/Catalogue/ubc-bookstore/supplies/general-stationery/writing-supplies/pencils--erasers/pentel-white-hi-polymer-eraser-large) - [AsinSight: best-selling polymer erasers on Amazon (US)](https://www.asinsight.com/report/US/polymer-eraser)
