I have a new project that I will need a a half dozen 25ml - 50ml test tubes for. As long as they fit in that size category and are the same size they will work for me. So if anyone has access to any let me know. I figured I’d ask around before I bought a case, when I only need a couple. This is a decoration, so it doesn’t matter if they have been used and may have trace amounts of cat drool in them that would throw of a scientific test, etc.
