We have two designs of inserts. The Original and the new Redlines. Both 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. Do not put customized cars in any foam product for a minimum of 90 days. Paint needs to gas out.

Our inserts are die cut to fit a variety of popular cars in the 1/64 and 1/50 scale car sizes. The cavities change in size both width and height. Each insert will hold twelve cars. Nine inserts (3 layers) will fit within one Hot Case; this totals 108 cars in one Hot Case.

Our Original Insert fits a variety of cars, for example the largest cavity (first column, third row) will fit a Dairy Delivery or VW Drag Bus. The cavities range in size increasing in size from top to bottom and right to left.
On our New Redlines Insert we eliminated the larger row of cavities and replaced it with a second row of thin cavity to better the fit for a majority of redlines. We also added an arch in the middle to better hold the cars without pinching the axles.
