Approx bathbomb weight 60-65g Our professional resin moulds are light and easy to lift and use, and unlike cheap 3D printed moulds,strong enough to withstand constant use - even from a pneumatic press. The smooth interior gives a perfect bomb time after time. You will not find these moulds from another UK supplier. PLEASE NOTE: Our resin moulds are hand poured and occasionaly may have slight imperfections from "popping" air bubbles". Please be assured that this does not in any way effect your mould. It just makes it unique to you.
