10" x 18" x 3" Reusable No Seal Forms

10” x 18” x 3” reusable form is the most affordable of it kind. Made of 3/8” HDPE, the sides are 3“ high and are welded together to create a tight seal that never requires sealing. 

Simply turn the form over once it’s cured and tap the back with a mallet and watch your creation pop out of the mold. The sides are welded at a 5 degree to allow your project to drop out.
