This is an aftermarket product imported from overseas. This is a set of stickers featuring the "Gibson logo" made from genuine abalone (awabi shell), and the "crown inlay" shape used on the headstocks of high-end acoustic guitars such as the SG, 335, ES series, Southern Jumbo, Hummingbird, and Dove. The G logo is the type with the dot on the "i" separated, and the crown is the 1950s style with thick, deep grooves. Also, while the previous type had a slightly darker color, both types now have abalone patterns that are quite thin. This is the same thinness often used for position markers on the neck. They are stickers, so simply peel off the blue backing sheet and transfer the entire sticker with the protective film on top. Then, slowly peel off the transparent protective film. The thickness is approximately 0.15mm including the adhesive layer. Please refer to the images for the dimensions of each part.
