Engraving on the back. Please see the third photo. A handmade leather brand that's trending on Instagram. Each item is handmade, and the texture of the leather seems to vary. It hasn't been used for a short period, but it has developed a nice patina and I think it can still be used for a long time. The following is from the official website: 《The Appeal of Genuine Leather》 radiant's concept is "simple and long-lasting items." Genuine leather has the appeal of aging over time. What is aging, anyway? Unlike ordinary items, it might be more accurate to say that leather products "evolve" rather than "age" over time. Personally, I think aged leather increases in value and gives off a deeper atmosphere. The change in quality and performance over time is called aging. The leather that undergoes aging: Only genuine leather that has been tanned with tannins (i.e., real leather) undergoes changes. The fact that it ages so beautifully without maintenance is the charm of high-quality Italian leather. Please try using genuine leather products and experience the appeal of aging ☀︎
