When you send a Neopet to another user through direct transfer all Neopoint clothing items presently worn by the pet will go with it.
— Any Neocash items equipped to the pet will be removed and returned to your closet.
— Any deluxe paint brush items that match the Neopet's colour will go with the Neopet, regardless if it is wearing them at the time or not. Even items worn by a different pet at the time will be transferred if they match the colour of the pet who is being sent.
