I got the same one as the other user and it's been great! As they mentioned it doesn't hold the chonky samples, but most of mine are skinnier samples anyway. Word of warning though, this box showed me i have well over 100 samples, which I never would've guessed before this. They seem to fit in such small boxes when laid down, and when I realized I had way more than one ammo box worth I got those "oh shit maybe I have too many" pangs.
