Review on 🛁 Caydo 30-Piece Metal Bath Bomb Mold Set: DIY Crafting of Your Own Fizzles in 3 Sizes by James Wing

For a first set of bath bomb molds, they work damn well. As for the size, I thought I would only use the smallest one, but in fact I have used all sizes. All three sizes fit in 4x6 shrink bags and it's awesome. The only "cons" about them are that since they're aluminum, they can be dented if you hit them with a spoon or something to release a stuck bomb, and the rim will hold water if you throw them after washing too soon before the last batch, you might have an unexpected reaction (which is why I don't actually "wash" them, I just peel off the dried bath bomb material and hand wash only when necessary).
