Vacuum Tube Storage FYI

I have been looking for ways to store my different sizes of vacuum tubes with very little luck.Vacuum tube storage and display cases are not readily available unless custom made.For anyone else in this situation I have come up with an excellent and not too expensive way to store vacuum tubes.Go online and look up sun glasses display and storage cases, they are not very expensive and come in multiple sizes.They will hold from 8 to 18 tubes  and most are 6.5" long by 2" to 2.5" wide and 2" to 2.5" deep and are nicely padded so as not to scratch the glasses up, there are even some nice wooden display cases with clear glass or plastic tops.
