This is an item of stationery (paper or writing goods), or other small merchandise such as good-luck charms, mascot straps, et cetera.
These gloves are perfect for yardwork or heavy lifting! Knit in orange, each has an image of half of Nami's shoulder mikan-and-pinwheels tattoo in a traction-providing material. Put your hands side-by-side to see the entire tattoo! When you wear these gloves, you'll be able to grab and lift stuff more easily! It must be noted that these gloves are huge, too--like most work gloves, they're made for guys with large hands. Of course, you don't need to actually use them--they're perfectly happy just to be part of your "One Piece" collection, too!
