10mm Female to 14mm Male Glass Adapter by VGoodiEZ
Nice little piece of glass!
My Dynavap stems, especially my Simrells, all need the gentle touch of unfrosted adapters, so this helps a lot--
I've seen Simrells beat up by frosted glass, so any collectors need this adapter (or one for each rig if you're extravagant). I don't really want to scratch my Dovetail and Futo stems either--it took some time to collect, so I want to baby them a bit.
