Fight those dry lips! Never forget your chapstick again! ;)
Features a long thread with a tight fit. You can use this container for geocaching, too! It should be watertight, when in doubt, just add a fitting rubber seal ring.
It has a stable attachment for a keyring. I printed it multiple times, it always fits like a charm!
I designed this for a specific product, but it should scale easily to the size you need for your purpose..
