Well I learned a lesson and will never get anything that comes in these again. What a pain! Literally! My clumsy self can not open these without smashing the damn things. I've opened 7 without issue but just broke a 3rd and cut myself. There are no dots on mine like in videos I've watched. I was going to order a ampule breaker/opener on Amazon and it says I will get it by Oct 10th. Good lord! I don't want to keep wasting gear and cutting up my hands! My next step is to try a file to make a score line. These things are awful!
