Are you planning to be a pirate sometime soon? Ray O’ Bannon designed a nifty craft pirate paper hat and it comes with additional pirate eye patch.
The hat is not printed material but the eye patch is. You get to be a little bit creative making hat but it seems easy enough from the guide
It’s not exactly One Piece material but it does look a bit like the manga. Useful for Halloween costume
Model comes in PDF with english instruction. Model is from ravensblight
