Friendship Ring

Instructional Video - How to create this Connected Inventory

We want to sell a custom product, such as a Ring, that can be resized, and engraved, but has only one physical inventory.
By default, when we use product variants (to select the size, and engraving option), Wix assigns an inventory for each of the variant options.

By using Connected Inventory, our app links the inventory of all the variants, so when one is purchased, the inventory of all the other variants will be reduced as well.
