I did the white boston rounds so they won't show the discoloration of the lotion with the vanilla type FO's, with black snap lids. Plus you can't see the level of the lotion, when you put in 8 ounces to sell, it leaves shoulder room, which you need to shake, but it also looks like it's been used.
I use whatever is cheap, thescentworks.com when they have things on special I purchase from them, the rounder bottles I am finsihing up right now were only 17$ per 50, I really should have purchased a ton more. Vicki
