Below are a list of beetle skins you have made. You can replace the versions of your skins here, and purchase additional copies.
For Automatic Sales, you can set a GB or a SB price (or both) that you want to allow people to purchase your skins for. They will be able to automatically purchase your skin from the beetle skin viewer for the price set, plus the additional 100 SB copy cost, though the 100 SB will not go to you. To make it so this is not possible, simply leave the prices set to 0 for both options. You do not need to add 100 SB into the price as the system will do that automatically. Whatever price you set is what you will receive when the decor is purchased. Please note that by setting both a GB and a SB price, it means a user can purchase in either SB or GB, not a combined SB/GB price.
