[Regarding Acrylic] Acrylic is a useful, clear plastic that resembles glass. But it has properties that make it superior to glass in many ways. It is many times stronger than glass, making it much more impact resistant and therefore safer. Acrylic also insulates better than glass, potentially saving on heating bills. Adding to this favorable array of properties, a transparency rate of 93% makes acrylic the clearest material known. Very thick glass will have a green tint, while acrylic remains clear. <br>Notice: <br>1.Acrylic mould products, it may have a mark on the surface is normal, but not a crack. <br>2.We have registered UK trademark, if someone sell our brand name products, we will maintain all legal rights .<br>3.
