$45.53 $50.59


MAMMOTH is a 2 piece heavy duty bath bomb mold that is 6" in diameter! This mold is ridiculous. This isn't the biggest bath bomb mold we carry, but it's bigger than the biggest that anyone else has by far!

Mammoth makes bath bombs well over 4lbs each!! Embed with smaller color bombs, glitter bombs or toys, make giant bombs for luxo baths or to break up for multiple uses. Bath bomb lovers cannot resist a Mammoth Bomb.

Favorite Two Wild Hares to be first to see new products & sales as they’re posted. We carry over 100 bath bomb molds in many shapes. ❤️

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

I love this mould. The quality is amazing and it works perfectly. I have made my first tester today which is currently drying in a tub due to high humidity in my home but so far so good. I am in the U.K. but I will definitely be ordering more in the future

WOW! What a bath bomb! I'm going to have to play around with recipes to fill this bad boy! Excellent transaction on great products - I recommend!

Such an awesome bath bomb mold! It's large size offers a mini work out but after filling and failing a few times, I now await as this giant of a bath bomb dries. Couldn't be happier with this purchase and the quick shipping from Nicole.
