Seller FAQ’s

Encore is the dedicated site for buying and selling CostumeBox products secondhand. We’ve created this space for you to have the best shopping experience for finding and purchasing our secondhand items. All posts are reviewed prior to going live and your purchases are backed by Treet Protection so you’re guaranteed to receive the product that was promised.

Listing your item is easy! Simply click “Sell Your Item” in the upper right-hand corner, create an account (tip: use the same email you’ve used to purchase from CostumeBox so you can see your order history), and go through the listing process.

Once you’ve added all of the applicable information, click “Submit” for the post to be reviewed within 24 hours. After it’s reviewed and approved, it will go live. If there are any issues, you’ll receive an email asking to make changes before it can be accepted.

  • The product is an authentic piece
