The holders are made of Jesmonite, an eco-friendly and non-toxic compound that has a smooth finish. It consists of three individual cog shapes that are stacked to make one holder. These are perfect housewarming gifts for your colour-obsessed friends and will look beautiful as part of a festive table setting. Each piece is hand cast and sealed by me in a home studio. All the products have their individual characteristics and their own air bubbles too! You will rarely find two pieces that are the exact same, which is what makes them wonderfully unique. The centre diameter of the holder is approx 2.2cm so can be used with most candles. What is included? 3 wheel shapes in contrasting colours are stacked to make a holder. Candle not included. Please do not let the candle burn all the way through the holder. It may leave a mark. If the wax drips on the holders, you can scrape it off when dried. All the pieces are beautifully packaged in coloured tissue paper and placed in a cardboard box rea
