No more stickiness - with these storage boxes Acrylic resins are no longer a challenge for flat embedding. In combination with the Cocoon box, which withstands temperatures up to 70°C, and our flat embedding molds flat embedding of acrylic resins (LR Gold, Lowicryls, etc.) are now possible. Oxygen is no longer an issue with the Cocoon Boxes. These molds can be used for all resins except LR white.
