Amounts change quite a bit based on the usual stock of materials someone holds regularly. I've noticed lots of folks keeping things inside fishing kits or little metal chests.
I need a spot to keep my needles, syringes, vials, and filters together and tidy. At the moment they're just sitting in the packaging they arrived in, and my old house has hardly any room for extra things. It would be nice to combine everything in one area that looks normal. Since I already use a cooler bag for my peptides, it doesn't have to be special.
