Hello sir, the wide tongue buckle hole, which we call Borulu buckle, is opened only in our factory with large industrial machines during production. But if it is too big, there is a different method. First of all, there are belt shortening steps in the size chart in the product picture, I recommend you to look at it. Briefly speaking, there is a screw under the buckle. When you remove it, the buckle and the belt will separate. If it is how many cm long, cut it with scissors, then screw it back to the buckle. We wish you a nice day.
