Items that you have requested to swap via the Request Box are temporarily held by Purenista and delivered once the swap is completed.
You can check which items you have currently requested to swap by looking under the "Awaiting Other Party's Response" tab in the Request Box.
If the swap is canceled automatically because seven days have passed, or if you or the other user decide to decline the swap, then all items will be returned to their original owners, along with the corresponding number of Gift Labels.
