We have three designs of inserts. The Original, Redlines and Oversized. All inserts are made from polyester foam, a standard in the packaging industry. The chemical make up of polyester does not contain any acid that could be harmful to finishes. In fact acid is what decomposes the foam. The glue used to bond the two pieces of foam is hot glue melt.
Our inserts are die cut to fit a variety of popular cars in the 1/64 scale car sizes. The cavities change in size both width and height. Original and Redline inserts will hold twelve cars. Nine inserts (3 inserts per section) will fit within one Hot Case; this totals 108 loose cars in one Hot Case. Oversized inserts will hold eight cars. Six inserts (2 inserts per section) will fit in one Hot Case.
