This 4 pack of silicone resin coaster molds is absolutely awesome! I love the fact that i can do all 4 coasters at the same time and when they dry they are a set! I am doing a set for my mother for Mother's day, because she has wanted a set of flowery coasters for a couple years.. i have not been able to find any and now not only will she have them but I will have made them! They are large and super durable. They have a diamond cut edge so they look really classy too. When i am dont making the resin coasters, I am going to make some fancy bars of soap for gifts also!
