This is a 5lb loaf soap mold with sliding bottom by Bramble Berry that I purchased for $49.99 and the silicone liner for $19.99. They were purchased separately. This is a wooden mold where the bottom slides out in order to remove the loaf. The liner dimensions according to their website is 16.6" L x 3" W x 2.6" H. The capacity is ~5 pounds. This mold allows you to make 16 - 1" thick bars.
