So I think I’ve at least partially solved the mystery of Caps’ weird packaging.
Small amounts of lube can come out of the air port - so storing them in a bag, jar, or anything else that has them on top of each-other will mean some likelihood of slimy switches in the future. (I found this out the practical way…)
Not an issue if they’re packed like eggs.
Edit:
U4T’s on the left, Caps on the right. If you look close, you can see the right side has lube on the bottom of the drawer while the left side is clean. I put these in at the same time, having gotten both from @davisthegreat.
So - a word of advice to anyone that buys these thocky bois - keep the crate.
