The dissection pan is made from high quality stainless steel with rolled edges and a tapered side, which allows the pan to be stackable. The size is 11 length x 7 width x 1.5 depth inches. The pan is supplied with a blue plastisol liner. Plastisol is self-healing and will hold pins securely during dissection experiments. The product is made to hold up to multiple uses. The plastisol pads can be washed or replaced. The replacement pads are offered by GoScienceCrazy as part number 360-PAD.
