The rubber eraser is said to be roughly 250 years old. But for all its old age, the partner to any pencil has always had one major flaw. You can’t see what you’re erasing. Until today. Osaka-based stationery company Seed, who has been making erasers since the 1950s, has developed a translucent eraser.
Seed says they came up with the concept of a clear eraser 5 years ago. But it took years of testing before they arrived at the exact formula that would produce a translucent yet functional eraser that would not crumble.
The official name of the eraser is the Clear Radar, and you can look for them in stationery stores across Japan.
