A staple of any Japanese pencil case! "Matomaru-kun" means "the one that gathers" — the eraser dust clumps together into strands instead of scattering across your desk, and some even sticks to the eraser for easy pickup. Once you've used one, regular erasers feel messy.
This Kira-Kira version comes in 4 holographic sleeve designs. Order 1 for a random design; order 4 to get one of each!
