Great question! If you have a book or boxset that weighs more than ten pounds, you can create the listing normally and enter an exact custom weight for your listing. If you have a scale handy, please check the weight of the book as part of your listing process. In many instances, we may already have weight data for a given ISBN in our system, in which case we will automatically add that info to your listing.

If a book is listed at an incorrect weight - please reach out to PangoBooks support after the book sells with the full weight of the package and we'll be happy to edit the shipping label, at no additional cost to you or the buyer.
