I received excellent, patient and kind customer service from this vendor. The items actually arrived earlier than expected and when I believe I had an error, the vendor kindly dealt with the issues and let me know that she was there to make sure that I was 100% satisfied I definitely was. I also received a gift along with my package and a lovely hand written note. ( it's the details for me) I love the molds and I would buy here again.

Step 1
Place the bottom piece of the mold on a flat surface.
Step 2
Attach the bath bomb cylinder/sleeve around the bottom to create a stable frame.
Step 3
Fill the mold with your bath bomb mixture, ensuring it’s packed evenly but not too tightly.
Step 4
Insert the top piece/plunger into the cylinder and press firmly to shape the 3D design.
Step 5
Gently lift the top/plunger, slide off the cylinder, and remove the bottom base.
Step 6
Allow the bath bombs to dry for 24 hours before packaging or using.
Pro tip: Batter too dry cracks, too wet spreads. Aim for damp sand that holds when squeezed.

I’m new to bath bomb making, but I wanted to get a nice mold that would be easy to use. I’ve used it a few times already, and I think it works great. Every bath bomb turned out perfect.
