Our molds are made of PLA which is derived from renewable resources like corn starch or sugar cane.  To clean your mold, rinse under cool water and towel dry.  PLA is heat sensitive and can retain water, so molds should never be put in the dishwasher or soaked, and should not be rinsed with warm or hot water.
 
Molds are printed to order, so we do not offer refunds or cancellations on any orders. If you have any issues with any item, please contact us directly, and we will work with you. If you have any quality issues, please contact us directly.
 
To use 3-piece design:  Place the sleeve on the base.  Add your bath bomb mixture.  Place the plunger on top, and then simply press down hard. You can either push the top and bottom piece out of the sleeve by hand, and then unmold, or you can use the plunger to push the mold pieces out.  Wipe away any mixture on the inside of the pieces before making the next bath bomb.
 
To use 1-piece design: Place bath bomb mix into mold. Scrape off excess mixture so that the mix is flat (and will be flat when unmolded). Flip mold onto a hard surface (e.g. baking sheet) and lift mold off of bath bomb. If the mold does not lift off, tap the mold with a spoon or other utensil to tap the bath bomb out of the mold.
