Use the model number on the product box or instruction manual.
Identify the page, build step, part, quantity or numbered bag.
Add order details, evidence and your current shipping address in the form.
Circle or clearly mark the instruction page number, build step and exact part. Photograph the entire page so the context and quantity remain visible. If the supplied piece is incorrect or damaged, add a second close-up of the actual piece.
