Previously, such gifts could only be used in other slots because their number could not be transferred to the crafted gift. This is because the gift's record remains on the blockchain.
Now, after crafting such a gift and minting it on the blockchain again (with the same number it previously had on the blockchain), the letter ยซCยป will be added to the end of the gift's number, indicating that the gift has been crafted.
Crafting these gifts is currently only available on test server.
