This is a double loaf skinny slab soap mold by Workshop Heritage that I purchased for $85. It comes with the wooden mold, silicone liner, and a wooden lid. The liner dimensions according to their website is 10 x 5 x 4 (L x W x H). The capacity is ~110 ounces (6 pounds). This mold allows you to make 2 skinny 10 inch long loaves for a total of 20 - 1" thick bars.
