The regular market holds 5MM and 8MM acrylic products. The Premium Acrylic - Pokemon Booster Box (6mm) is the first one to change the thickness to 6MM thickness. This small detail opened up the opportunity for us to put the strong N52 magnets on top without cracking the case. By using ‘virgin acrylic’ materials imported from Taiwan, we can guarantee a high quality product. The case has a 83% UV-resistance rate and we finished it off by polishing the edges to make the case smooth and elegant.
