36 Bar Bottom Insert: This is an optional insert for our awesome 36 Bar Baltic Birch Wood Molds. Made from the same heavy plastic as the side borders. The bottom insert is a flexible plastic that can withstand constant temperatures up to 200° F (but please do not subject them to temperatures over 200° F).
Please note: It can be tricky to remove your soap if your recipe is a little soft or slightly sticky. Just be patient and gently slide and spin the soap off and you should be fine.
