I used these to make single serving hot cocoa gifts. The tubes work great! Wish the labels stayed on better. A little tape over them helps though.Picture is misleading- the test tube holder does not come with the test tubes and they are an odd size so buying a test tube holder won't workThis product is what I needed for a craft project, BUT the labels become unpeeled within 24 hours. I had no other choice but to reattach them with some clear tape, which was fine, but it would have been nice if they stuck.I wanted to make a spice rack with test tubes. But I cancelled an order for the real deal because of reviews of the glass breaking and my husband felt glass was not a good idea. So finally I bought these and I LOVE them. They are huge. I constantly tried looking for exact specs because there is some contradictions out there. They are pretty huge. You can get tons of a spice in one.These worked out great for the project that my 8 year old was working on.These were exactly as advertised. I couldn't quite figure out the labeling on them but it really didn't matter. Any computer can generate labels on sticker paper.Love these vials. I made bath salts and used the test tubes to give as gifts. Super cute packaging with a label and jute wrapped around it. Will be buying more.I was disappointed that the chrome holder didn't come with it. That was the main reason I ordered it. I haven't used it yet because I have no way to make the test tubes stand up.
