Recently, the number of D buckle types has been increasing.
The D buckle can be attached to a leather belt just as easily as a metal belt, and can be removed easily.
What's more, the leather has the advantage of not easily deteriorating, so some people are replacing regular buckles with D buckles.
However, some people may be a little confused when wearing it for the first time.
Once you use the D buckle, you will find it convenient.
I would appreciate it if you could use it as a reference.
