These One Piece signature collectibles are mainly for display and collection purposes. To show them off, you can place them on a shelf in your room or use a display case. When handling these items, make sure your hands are clean to avoid getting dirt on the autographs or the collectibles themselves. Store them in a dry and cool place, away from direct sunlight as it could fade the autographs over time. Remember, each signed item comes with authentication, so keep the '7BAP Signature Series' sticker and the third - party authentication (usually JSA) safe. Also, as the signatures may vary from each other, don't expect them to look exactly the same. And please note that there are no returns or exchanges for these Signature Series items.
