I had 5 or 6 tubes of cement when I moved last year. Three or 4 were completely empty. They looked full, but when squeezed nothing came out and they just flattened down. Another had leaked, another was almost gone, and the last one had a split cap. They were all generic garbage but even so, the pathetic performance pushed me to buy the can.
now I'm looking at other containers. I think I'll use a glass jar for the bulk of it and try the little dishes that THC concentrate comes in to carry on the bike. I found one type of dish that has a fully plastic lid and that's the closest thing I have to a vial.
I saved an empty hand soap bottle with the pump. That would be weird but I think it's too large.
