Custom Geode Bookend Silicone Molds

These custom Geode Bookend molds come in two shapes giving you a choice in how you use them! Create two identical bookends, one at a time, or two different but complementary shapes for an organic look. The bookends from these molds measure 4.5" x 3” and 5" x 2.75” and each mold takes approximately 400ml of resin. Note: Because these are hand-made molds cast from real geodes, there could be small lines or marks in the molds reflecting actual stone.  Tips (always follow instructions for the resin you are using - these are meant as general guidelines): Always pour your resin into the hardener (pour hardener into the mixing container first, then resin).  Stir resin with a plastic or silicone stirring stick to reduce air bubbles. Wood is not recommended as it can create air bubbles. Let resin sit a few minutes after stirring to reduce air bubbles. Don’t use a torch or heat gun as it could damage the molds and make it difficult to de-mould, causing them to tear - this is especially true
