When two variants share the same product name, the SKU is the quickest way to tell them apart. Saving it is especially useful when you buy the same jewelry in different sizes or finishes.
Keep the SKU with your notes
Copy the SKU from the product selection or the order details. Add a short description such as the color and size so you can scan your notes later.
Search before you reorder
Paste the SKU into the storefront search. Open the result and review the selected options, current price and stock. If you use Buy again from My orders, check the quantities and availability in your cart.
