One-to-one customization is a self-proclaimed imitation seller. Since it is imitation, it is naturally not original. But for ordinary people, it is good to buy one-on-one customization, at least you are the same as the big-name style.
If you want to ask if it is reliable, you should choose a regular shop. Generally 1 will choose the same material as the genuine one. As long as the material is ok, choose a shop with better workmanship.
