Hello! We've just finished a custom from a really nice customer that used a makeshift box gunge tank. It's definitely not a high-tech professional thing but it works! This is the second one we've made. Slightly narrower than the first one.
I think I might get two or three more sessions out of it, but we're looking for ideas or scenarios or clothing or substances or anything really that gives some inspiration for what to do with it!
If you have any, do feel free to leave them . No promises of fulling any requests of course, but thought I'd ask around and see if there were any good ideas we could borrow
