This is a small box for Dremel bits (or any similar bits).
The holes are around 3.5mm, so they can hold most dremel bits without issue. The maximum bit length is around 45mm.
The box is 50mm tall, around 45 mm wide, and 18mm thick. It can hold a variety of routing bits and some bigger ones (there's 4 holes that have bigger clearance for them).
