How to Use

Mix your epoxy resin as per the manufacturer's ratio, add your chosen pigments or inclusions, and pour slowly into the mould. Allow to cure fully on a level surface — typically 24–48 hours for epoxy resin. Once cured, flex the mould gently to release the piece. Sand edges lightly if needed for a perfect fit between lid and base.

Safety Tips

Always work in a well-ventilated area when handling uncured resin. Wear nitrile gloves and avoid skin contact with liquid epoxy. Keep resin and mould materials away from children. Do not use this mould for food or candle purposes.
