Want your resin teardrops to look like real gemstones. This mould has a faceted pattern so that your resin castings will look like the genuine item! Each teardrop measures 2.5cm wide by 4.8cm long by 1cm deep. Leave the castings with a flat back or glue two together. This mould contains 24 cavities and holds a total of 150mls of resin. How to Use Resin Moulds: Remove any dust, etc. from your mould. This resin mould is reusable and made of durable, smooth polyethylene or polypropylene. Moulds do not require mould release when casting with resin, however, it is strongly suggested. We recommend the use of Castin' Craft Mould Release/Conditioner. Instructions: Protect work area with freezer or wax paper. Treat moulds with mould release/conditioner. Place mould tray on level surface. Fill mould cavities just below top. Once pieces are cured, turn tray over and press centre area of each piece to release, flex if necessary.
