The capsule fit is a bit tight in a few slots, but the cardboard sides flex enough to allow the capsules to squeeze in snugly, so there is no chance of the capsules falling out.

The box is a nice way to orginize the capsules. If you have a lot of the same type or close to the same, they fit in about the same box. I really like the box. I have plans to buy more.

These/this storage box is great for me to keep my coins in order and neatly put up. I am really glad I found them/it.

Good looking easy to use

The pieces fit together just right, Not too tight, not too loose. This, along with the storage box, is going to greatly simplify storing whatever.
