Kanebo Custom Compact Case I don't have the refill, so I measured the inner dimensions of the case: Length: Approximately 3.7cm Width: Approximately 6.0cm There are bumps inside, and it has a snap-in structure. The brush compartment is about 2cm long. ◆ This price is due to the white marks from using nail polish remover to wipe it... The area for the sponge/applicator is intact ❦
