Laugenstein soda lye (sodium hydroxide) tin with skull and crossbones. Price is for one tin. Soda lye is used for soap making, cleaning grease and drains, as well as other manufacturing uses. It is caustic and highly corrosive. It causes chemical burns if it comes in contact with the skin and permanent blindness upon contact with eyes. These are unused (at least I think they were unused) containers. They some some age, surface rust and wear but are pretty decent. All are in similar condition.
