Where to buy engraved maps, where to buy gray maps, and how about after-sales service? JD5.20 I am the buyer.

You can search for "engraving" or "engraving" on Taobao.

The difference is:

Engraving maps are ready-made maps, and there is no after-sales service. You can buy what you are satisfied with, but don't buy what you are not satisfied with.

Carving is selling time, designing relief drawings according to your drafts or pictures. This kind of carving must have after-sales service, and minor repairs and minor repairs are included in the after-sales service.

In terms of price, the current maps are generally a few dollars or a dozen dollars, and there are also packaged galleries for sale. Thousands of dollars to buy tens of thousands of line charts; Drawing is generally based on the complexity of the picture, starting from a few hundred yuan.

I hope my answer is helpful to you.
