Over time, I have collected quite a selection of flavors from different vendors. I would just kind of line them up in a neat order and such so it didn't look so discomboberated. But every time I wanted to get a flavor, taking a bottle out and putting it back would scatter how things were set up. I decided to take one of each sized bottle to Home Depot. I had seen 2 ft lengths of pvc piping for sale and thought if I just got the right size, I could build a rack where everything was in it's place. I cut the pieces about 3/4" lengths and superglued them into whatever layout I wanted. This holds my 15 ml TFA bottles, the 30 ml from vendors as well as my clearomizers. For a little more ease, I set this on a Lazy Susan.
