This is a denture that will help if you lack confidence in your own teeth due to yellowing, chipping, or gaps. One box contains upper and lower dentures. I will list another box. I bought one box for 4000 yen. I bought it by mistake. How to use: First, melt the gutta-percha until it becomes liquid. Then, attach the denture with the gutta-percha. There is no seasonal feeling. It can be used all year round. There is no color.
