Package Contents:You will receive 8 Halloween themed diamond coasters, 1 coaster holder, enough coloured diamonds, 1 clay adhesive, 1 pen and 1 diamond tray for your creative needs. High Quality:Our Halloween diamond coasters are made of high quality wood and acrylic material with classic Halloween elements in the design. The patterns and numbers are clear and easy to read. Strong adhesion makes the rhinestones stick firmly to the coasters and not easy to come off. Easy to Use:Our DIY diamond kit comes with tools to help you make it. The production process is as follows. Firstly, peel off the film of the coasters, then pick the diamonds you need according to the number of coasters. Finally, glue the diamonds onto the coasters. Non-slip Cork Backing:Each diamond painting art coaster has a natural cork pad that protects furniture or table tops from scratches or abrasions and keeps the coasters stably fixed in place - protects your table tops and countertops from heat and won't stick to glass.
