Yorker caps

[Whitaker2472]

Has anyone used the yorker caps from bull city vapor and just leave them on the bottles. Will they seal up good enough to just leave on?

I wouldn't use them for nic, but they work fine for PG & VG.

Im just using for flavorings.

As long as they aren't alcohol based, it should be fine.
