haha, I maaay have a slight problem... =/
and they're ammo boxes! I actually got the idea from this sub, they're perfect for sample vials! this is the one I have 4 of, its the perfect size for the shorter 1ml samples. and this is the bigger one I have, which works great for the taller 2ml samples, edp samples from sixteen92 and deconstructing eden, etc. and they come in different colors, I just like blue. =)
I can't include every vendor's name, there are just too many so hopefully that sizing photo will help you. I haven't included Sixteen92's 2ml sample in a case because I just put mine in the side of the Plano 12 or 16 Gauge box.
BPAL's imps are also 1ml. BPAL full size fits, tight into a 10-12 gauge ammo case.
For 1ml vials (BPAL Imps, Solstice Scent samples, etc) THIS case works perfect. (Search Amazon: MTM 38/357 Cal 100 Round Flip-Top Ammo Box)
For full size bottles (BPAL, Madame Josephine Rollerballs, Solstice Scents full size roller balls) THIS case works. (Search Amazon: MTM 25-Round Magnum Shotshell Box)
For Cocoa Pink drams, Smelly Yeti samples, Alchimia Apothecary samples, ThreeTenLabs samples, etc. THIS case works (Search Amazon: Plano Shot Shell Box, 12 & 16 gauge)
I hope this helps! :)
