Piercing Clay Tool for Roller: This tool facilitates the easy piercing of holes in polymer clay beads. It accommodates 10, 12, and 15 mm round beads and works exceptionally well with a polymer clay bead roller, effectively addressing the challenge of creating multiple sizes of polymer clay beads. Perforation Positioning:The fixed perforation positioning design enhances convenience and simplifies auxiliary perforation and drilling tasks. Easy to Use: Simply place the polymer clay bead into the corresponding size slot, close the lid, and push the needle through the hole in the lid. This allows for precise center hole placement in your polymer clay beads. Tough and Reliable: The clay bead hole maker is constructed from premium plastic material, ensuring durability for long-term use. It is ideal for crafting various items such as clay earrings or necklaces. Kindly Reminder: We recommend applying cornstarch before using the bead hole punch to prevent sticking. For maintenance, wash the molds with warm soapy water or wipe them down with alcohol; this facilitate convenient storage and preparation for use.
