Patelai 12 Pcs Portable Keychain Pill Holder Mini Pocket Pill Case for Men Women Aluminum Geocache Containers Waterproof Metal Medicine Bottle Organizer for Outdoor Camping Travel(Black)

Air tight, its all aluminum, good value, no complaints.

A little small. Can only hold a few pills

These pill containers work great for 1 normal capsule & 2 smaller round pills. I carry mine for my seizure meds. I have a Keychain on every bag I own. They are a perfect size & are sealed up tight & secure. Thank you!

I was hoping to tote some essential oil in these. They arent made for that, but i thought id give them a shot anyway. The O-ring doesn't hold up well enough for that, but I use them anyway. I have them clipped to my backpack, and they leak "just enough" scent to keep a light, pleasant aroma around me. My next move is to replace the current O-Rings with commercial grade O-Rings. However, I'll leave the containers on my bag as is. I love the light aroma.

only received 11 of 12 of the pill boxes

Good quality, decent price.

I put them on key ring and zippers on bags, as they seemed well made. However after being in my pocket all day I discovered they will pop open - pills in my pocket and the bottom part missing. Couldn’t solve the mystery, and it happened twice. Maybe tangential pressures on threads?? But then where did the bottom tube go?

I purchased these for geocaching. They work just great. No issues. I would buy again.
