This is the genuine sponge foam for Pelican Case 1510. (It can also be used almost perfectly with 1535) The thin bottom foam and the wave-shaped foam for the lid are not included. These are the two middle layers needed for rearranging the items to be stored. The Pelican case itself is not included. There is some discoloration on the surface, but the softness and flexibility are not affected. As shown in the photos, there are small grid cutouts, and a camera was partially stored in it. A few blocks are missing, but please tear them out to your desired shape to fit the items you want to store. It can be used almost perfectly with the Pelican Air 1535, but only one layer. As shown in photo 8, the height is slightly insufficient, and there is space for one book. It will be placed in a plastic bag, taped, and shipped as is. It will be just under 100 size for shipping.
