For the inlay I use different materials such as metals (copper and melchior); white wood (Latin name is evonymus) and turquoise. The bowl is covered with natural watersle and can be used in everyday life without any problems. I make 2-3 layers of lasca on finished work with organic materials and like the last step of sandpaper them. This is the technology used by our family. With our works, we participate in many festivals and exhibitions. I hope you will enjoy our products as they are unique and made with great care and love for you. This item is made of wood.
