Sakura of America's EE-3000 page (read November 2, 2026) and Blick's listing give no country of manufacture, so check the package. Sakura Color Products is an Osaka company; its Japanese site did not connect from our network on November 2, 2026. - Good for: Drawing and sketching, Travel. Skip it if you want a cheap plain eraser; this one needs AAA batteries and costs US$45.31 at Blick. ## Key takeaways - Sakura lists more than 10,000 RPM from a quiet motor with strong torque, for removing graphite marks and fine details. - The unit measures 25.48 mm wide, 127.8 mm deep and 31.42 mm high and weighs about 2.9 oz (82 g) with batteries. - It runs on AAA batteries for approximately 4 hours of continuous use, per Sakura; Blick says it ships with two batteries and 20 pencil erasers. - The body is durable ABS plastic, round and ergonomic, for long periods of use. - Blick sold it for US$45.31 on November 2, 2026, in our $$$ band ($20 to $75). ## What is the Sakura SumoGrip EE-3000? **It is a battery-powered pen-shaped eraser for small, exact corrections.** Sakura of America says its round, ergonomic body suits long sessions while keeping pinpoint erasing accuracy, and that the AAA-powered motor ditches the cord of bulky AC electric erasers. The motor turns at over 10,000 RPM with strong torque, which Sakura says makes graphite easy to remove and fine details easy to create. We read Sakura's page on November 2, 2026. For Sakura's block eraser, see the [SumoGrip B80](https://stationerytimes.com/guides/sakura-sumogrip-eraser/). ## What are the specs? **The numbers Sakura gives are speed, size, weight and run time.** | Spec | Value (Sakura of America, Blick) | |---|---| | Motor | Over 10,000 RPM, strong torque, quiet | | Power | AAA batteries; about 4 hours of continuous use | | Unit size | 25.48 mm (W) × 127.8 mm (D) × 31.42 mm (H) | | Weight | About 2.9 oz including batteries (82 g per Blick) | | Body | Durable ABS, round and ergonomic | | In the box (Blick) | 2 AAA batteries installed, 20 pencil erasers | | Price | US$45.31 (Blick, November 2, 2026) | Not stated: eraser stick diameter, noise level in decibels, battery brand, country of manufacture. ## Who is the EE-3000 for? **It suits people who erase small graphite areas often and carry a kit.** - **Drawing and sketching:** Sakura lists cartoon drafts, drafting and architectural plans, and a pinpoint eraser driven at over 10,000 RPM. - **Travel:** It is cordless and weighs about 2.9 oz (82 g) with batteries at 127.8 mm long, which Sakura calls compact and geared for mobility. Skip it if you want a cheap plain eraser; this one needs AAA batteries and costs US$45.31 at Blick. ## How is it different from a block eraser? **It lifts graphite with a spinning stick instead of rubbing a block.** Sakura contrasts it with bulky AC electric erasers, not with hand erasers. Sakura's block eraser, the [SumoGrip B80](https://stationerytimes.com/guides/sakura-sumogrip-eraser/), is a hand tool you press and rub; the EE-3000 is a powered tool that works on one spot. That comparison is ours; Sakura makes none. Our [best Japanese erasers](https://stationerytimes.com/guides/best-japanese-erasers/) roundup covers the hand-held kind. ## What does 10,000 RPM mean in practice? **More than 160 turns a second.** Sakura says "over 10,000 RPM", which divided by 60 is above 160 revolutions each second; that arithmetic is ours. Sakura pairs the speed with strong torque and a quiet motor, and with about 4 hours of continuous use, or roughly 240 minutes, from AAA batteries. It gives no noise figure and no test, so the claims stay the maker's. ## Which erasers does it use? **Pencil-style erasers, and Sakura sells refills.** Blick says the box holds 20 pencil erasers, and Blick lists cordless electric eraser refills as a separate item. Sakura's page names no refill part number or eraser diameter, so check the listing before you buy spares. ## What do we not know about it? **Sakura's page is about graphite.** It describes removing graphite marks and fine details in artwork and says nothing about ink, colored pencil or paint. It also gives a battery life of "approximately 4 hours of continuous use", without naming a battery brand or the test conditions. Blick says it ships with two fresh AAA batteries installed and carries a note about installing them, so read that note before the first use. We have not run the motor ourselves, so treat run time, noise and erasing power as Sakura's claims. ## Where is it made, and what does it cost? **Sakura doesn't say where it is made.** Neither Sakura of America's page nor Blick's listing names a country. At US$45.31 on Blick (November 2, 2026), it is in our $$$ band ($20 to $75). Prices change; check the listing. ## Frequently asked questions ### How fast does the EE-3000 spin?
