Description
An eraser that looks like a geometric object—and works better precisely because of that.
Reuleaux tetrahedron
The shape is formed when you arrange four spheres so that each one touches the other three, and then take the intersection of the spheres. The result has four curved edges and four tips. In practice, this means you always have a fine tip at hand that lets you remove a single line without smudging the surrounding drawing. If a tip wears down, simply rotate the body.
What is it for?
- Remove Individual Construction Lines from Sketches
- Erase larger areas across the curved edges
- Fits AEON graphite leads and any standard pencil
With the Eternal tip, it doesn’t erase as thoroughly because metal—rather than graphite—is in contact with the paper.

Who it's for
A good fit
- Anyone who wants to erase single lines precisely instead of smudging whole areas, thanks to four fine edges
- Anyone who draws with the AEON pencil and graphite tip
- Anyone looking for a desk eraser that also looks good as an object, shaped as a Reuleaux tetrahedron
Less of a fit
- Anyone who wants to erase lines made with the Eternal tip: the graphite tip is the better choice for that
- Anyone who leaves the eraser near a radiator or window, as heat and sun make it hard
Frequently asked questions
A Reuleaux tetrahedron is a geometric shape with a constant width at every point. Stilform chose this shape because it fits securely in the hand and allows for precise erasing from any angle—no slipping, no tilting.
Yes. The eraser is designed to erase cleanly, and based on users’ experience, it doesn’t leave streaks—even when erasing graphite marks from the AEON pencil.
This eraser is the perfect companion for the AEON pencil and all other graphite pencils. However, it works with any pencil—regardless of the brand.
The eraser is made of rubber and visually reflects the minimalist design aesthetic—a small accessory that complements the rest of the collection perfectly.
