VIDEO: HOW TO CARE FOR YOUR SILICONE MOLDWhat in the world is a Jumble Box™? A Jumble Box is an adjustable mold that can be arranged into various positions for casting different shapes. The Jumble Box is APPROXIMATELY 6"(15.2cm) square by 1½"(3.8cm) deep allowing you to make cubes, rectangles, wedges and triangles just by repositioning the inside molds. As an added plus, the two movable sections are also usable molds. Each one allows you to create ¾"x 1½" (1.9cm x 3.8cm) tall rectangle posts. Jumble boxes are great for making showpiece bases, posts, encapsulation or thin plates for bending and shaping. The good news is that for one price, a Jumble Box can help you create over 100 different shapes!To see how the Jumble Box is used, please visit Tips & Tools on our web site.Made of food contact safe silicone.
