WITH PACKAGING: Our coasters can not only be used as birthday, Valentine's Day, and Christmas gifts for your friends and family, but also for art classes, parties, home decor, and other DIY projects. Cork Coasters - Each coaster has a natural cork pad that protects furniture or tables from scratches or abrasion, keeps the coasters stable, protects your tables and countertops from heat, and won't stick to the glass. Steps - First, peel off the protective film on the coaster, then find the desired rhinestones according to the numbers/letters on the coaster, pour the corresponding amount of rhinestones into the tray, polish the coaster with a pen, then pick up the rhinestones with the pen and stick them onto the corresponding numbers/letters. Finally, attach the cork pad to the back of the coaster.
