3.5″ BATH BOMB Mold, Heavy Duty, Stainless Steel, Almost Softball Size, Wont Dent!

Shipping to United States: $4.99


This 2 piece heavy duty stainless bath bomb mold is 3.5″ or 90mm in diameter. This mold makes the giant sized bombs like you see at L*sh stores. It’s great for embedding with smaller color bombs, glitter bombs or toys. This is a very big mold to make bombs for giant tubs, luxo baths or to break up for multiple uses. It is just slightly smaller than a regulation sized softball ( which is 3.8″).

These molds match up flush on the rim when forming bath bombs, can take rigorous tapping & don't dent with tapping. These are forever molds & bath bomb making is just more enjoyable with better equipment. Start with the best!

This listing is for one set of 3.5″ heavy duty stainless steel bath bomb molds. Any other sizes or products shown are for example only.
