It depends on the size of the toys. Something small like bullets, egg style vibrators, and compact toys, you'll obviously be able to fit more inside of it. If you have insertable vibes or dildos, you might be able to get two or three. It really is a very small storage box.

This case is cute, but it's not very big. It only measures 4" x 4" x 12". So the number of toys will vary greatly depending on the size and shape of your toys.
It will hold many small bullet type toys or just a few larger toys. Did you check out all the pictures at the bottom of the product page? There are lots of pictures that users have posted showing what they were able to fit in theirs.

Like the other posters have said, it's a *really* small box. You could pick up a locking tool box to hold your toys instead as an alternative! They're not terribly expensive at Walmart, and I've even seen coloured ones like pink and blue.

I just went out and box a box from Target to store my toys. Bigger, and more affordable.
