Came in bulk bag! Perfect for my use! We use them for seed storage! Fits 15 seeds eassssy! Thank ya again

These will perfectly for what I need them for. I am a geocacher and I plan on using this for my hides. If you are not famiar with geocaching give it a Google and check it out. As for other cachers this review will help you. This batch of 200 are A lot smaller then the ones everyone is usually using on stop sign holes and things. Intact it won't fit into a sign like hole unless you plan on scrappy them.once or twice with duct tape. However these a GREAT for implanting them into drilled out golf balls or dead trees you see lying on the ground. Simply take a small drill bit and drill your hole and insert. If you do it small enough u can force the tube in and it won't fall out. The caps on my batch fit tightly so I doubt any water will seep Inside to ruin your log however there's no way kind of swag is fitting in here unless you want to trade specks of dirt lol! I highly recommend these for those evil very very evil extremely evil geocache hides we all hate and love!!! Can't beat this deal just know theyare larger if you don't want the super tiny ones these are.

I put a hole in the top and use these for scent training. I dip a q-tip in the scent and put it in here. I hide these and the dogs find the scent.
