Here's 1 of the long, smaller cases. The only place that the 30mL glass and plastic bottles
won't fit standing up...is the area right under the handle, since it's recessed into the lid. I keep some of my smaller 10-15mL bottles of newly acquired and infrequently used flavorings in that section.
The reason there are gaps in the numbers on the bottles is because these are some of the 30mL sizes used to refill the other numbered smaller vials/bottles kept in my larger, main mixing case. There are also flavorings with some other numbers in the 4oz. size bottles, in a PM box.
ETA: I just counted the bottles in the case, and there's (29) 30mL, and in the section under the handle...(15) 15mL, and (3) 10mL in there. There's 3 other 10mL ones poked in between some of the 30mL bottles in the last 2 sections on the right.
