Cartridges are fine. I'm not sure I'm totally sure about the effectiveness of the cartridges. Care should be taken when casting drill bits. I highly recommend doing this over a container so if you spill something you can sweep it into a corner and dump it out. This case is not meant to be carried around. The handle is not strong and the latches to close the case are very weak. I won't risk using a pen as the lid might open. The cartridge caps and opening tab are not tight enough and I can be sure that if they fall out they will stay closed. I advise you to use this case only to store drill bits. Don't take it to work on ongoing projects. I use it for extra exercises. It stays in my craft area. I will continue to buy the best take away bag.
