Review on WARMBUY Metal Bath Bomb Molds by Denise Davis

We love this shape my 9 year old has made a lot for sale and home use. The mixture comes out easily, never sticks. Two observations: a) Yes, the diameter of the mold is 6.3 cm or 2-7/16 inches (ie almost 2.5 inches) and is larger than described. This can be a problem with your packaging, so get a larger bag. The mold is 8.5 inches in diameter, so a 4.25 inch bag should suffice. b) We don't add water to our mix, I think that's a mistake that will cause bubbling and uncontrolled growth. You can't force the mix to stay compressed in the mold when water is present,
