This 3D resin wall painting by XS Studios features Luffy from One Piece using his Gear 4. In Gear 4, Luffy extensively uses his Busoshoku Haki by coating his arms, legs, and much of his torso to the point that they turn black from hardening. The Haki coating across his body resembles the wispy ends made from flames, giving it the appearance of tattoos, and he gains shading around the inner and outer edges of his eyes. This is made of PVC and resin.
