I want to make my diy flavors more accessible. a year ago I got a sample tin from halo. inside the tin was a piece of foam with holes cut out. inside the holes was the samples. im thinking I could get a foam pad and do a variation of that. with a foam pad I could take a knife and make a X cut in the foam. each X would hold bottles of varying sizes. I use the foam from halo still. very handy for holding anything im working with including rbas bottles tanks etc.
