These reusable silicone moulds are intended to cast concrete cups shown on the photo — smaller and bigger one — with the same faceted pattern on the walls. The moulds are ready to use and do require any additional casings or inserts. With these moulds you can make concrete pencil holders/planters/cups/tumblers/candle containers with the following dimensions: SMALLER: 6 cm (2 in) high; 7 cm (3 in) across; 0.5 cm (0.2'') thick walls BIGGER: 9 cm (3.5") tall; 9 cm (3.5") across; 0.5 cm (0.2'') thick walls; 300 ml (10 oz) volume Mold is tested and proven to work with concrete without breakage. Final result depends on concrete mix you use. Casting results and mould durability depend on used mix, usage and care. Silicone mold is made from very flexible, stretchable, durable platunim-grade silicone. This mould works best with de-moulding/release agent. Fast and reliable shipping from Central Europe.
