Plexiglas Box Black Bottom Collecting Minerals Fossils Shells Insects Butterflies Coleopters

Plexiglas Box cm 8.3 x 6.3 x 9.6 h Container for Collection Minerals Fossils Shells Entomology Insects Butterflies Coleopters or other Arthropods.
In Transparent Plastic (PMMA), black bottom, two interlocking pieces, as in the photo.
N.B. These boxes all have the same slight grooves (visible more with incident light, see photo) due to a manufacturing defect produced by the machinery during the printing phase.
It is recommended to fix the samples inside with plasticine fragments, at this link.
Also available Cellophane Boxes with or without polystyrene bottom, or other kinds of Plexiglas Boxes.

Polymethyl methacrylate (abbreviated PMMA) is a plastic material made from polymers of methyl methacrylate, methyl ester of methacrylic acid. It is a thermoplastic polymer.
It is also known by the trade names of Plexiglas (only one s), Perspex, Amanite, Lucite, Trespex, Vitroflex, Acrivill, Perclax, Limacryl, Crylux, Oroglas, Setacryl, Altuglas.
It is normally very transparent, more so than glass, can be recycled, has a higher breaking point than glass, is softer and more sensitive to scratches and abrasions; this is generally remedied with an appropriate covering; any scratches can be easily eliminated thanks to specific polishes, unlike glass it does not block ultraviolet and infrared light, it can be cold welded using cyanoacrylate-based adhesives or by dissolving the surface layers with a suitable solvent - dichloromethane or chloroform. The joint created is almost invisible. The sharp edges of the PMMA can also be easily polished and made transparent. PMMA burns in the presence of air at temperatures above 460 °C; its complete combustion produces carbon dioxide and water.
Not to be confused with polymethylacrylate, a polymer that looks like a soft rubber.
