Originally purchased from Cada molds. 
The Bath Bomb Final Size - 7.6cm (3") Wide x 7cm (2.75") Tall  (Thickness will vary depending on the amount of bath bomb mixture put in the mould)
This set comes with the interchangeable pucks to create a variety of conversation hearts:
KISS ME
BE MINE
XOXOXO (2 of these - not sure how I ended up with 2)
HUG ME
I 💗YOU
The set also comes with a full set of stencils to make the painting of the letters simple. The stencil has a lip that catches the outside of the bath bomb keeping it lined up on the bath bomb, preventing the stencil from moving around on the bath bomb while you are trying to paint it.
