Can a Seller substitute parts from my MOC?
Yes, only if the replaced part does not change the images and instructions provided with the MOC. The seller(s) of your MOC is supposed to sell the MOC as it is described in the parts list and instruction manual.
However, if you allow the Seller to substitute a part upon their request, a Seller may sell it. In all cases, the Designer must include appropriate disclaimers at the bottom of their item description.
When a part has been substituted but still appears in one of your photos and/or instructions, write:
For store [insert store name] only: Part [insert initial part] has been replaced by [insert substituted part]. This does not alter the original look and function of this model.
