"In the past, the sun became slow, horses and mail were slow enough to love only one person in a lifetime." This is an era when we like the new and dislike the old. We start to use one thing at will, and then quickly forget and discard them. The emotion between us and the product is getting weaker and weaker. So I chose the three materials of "solid wood and brass" for design. After use, they will oxidize and become old, resulting in traces that belong to you and the product.
