Hi everyone, I don't even know if that's the correct name for these tubes. I ordered some on Amazon and was disappointed when they came in, it was my fault because I obviously didn't read the complete advertisement. I wanted these to store my scroll saw blades in, but they were only 4 1/2 inches long, and we need at least 5 inches, the ones that were delivered to me were very sturdy and I'm sure they wouldn't break if they hit the floor. I would also like use these to store some specialty brad point drill bits, it would prevent the sdges of the drill bits from banging together. I'm sure I read on one of the forums that someone orderd them and the blades fit perfectly, this old brain doesn't want to cooperate in helping me find them on the internet. Than you in advance for any help finding these really nice tubes with screw on caps (Soda Bottles).
