Thank you for viewing! This was made through practice in woodworking and fretting. The materials are ebony and abalone inlay, giving it a high-end feel. Freedom SPNF04 frets are used. The side is slightly scalloped, making it less likely to hurt your fingers even with a gripping form. However, this product is a necklace, so unfortunately, you won't benefit from that. Also, the fret edges are slightly raised to prevent string slippage. However, this product is a necklace, so again, you won't benefit from that. The finish is linseed oil + beeswax wax, polished to a natural luster. The cord uses "FUJIYAMA RIBBON" cotton cord. The cord is set long, so if you want it shorter, please untie it and retie it to your preferred length. (It's best to cut off the excess knot for a better look.) Also, if the cord becomes twisted with use, you can lightly moisten it and dry it with a hairdryer to remove the twisting. A ball chain is included, so you can remove the cord and attach the ball chain to use it as a keyholder (image of the ball chain in use is provided, but it's just an image. The product in the image is not included, so please understand). Please be aware that color transfer may occur depending on the clothing. Also, there is a possibility of skin problems such as itching depending on the wood and skin type, so please check for any skin abnormalities before use. I have taken care to ensure there are no burrs (snags) on the fret sides, but as with regular guitars and basses, the wood may shrink over time, and burrs may appear. Please be careful not to snag your skin or clothing when wearing it. As this is a handmade item, there may be areas where the precision is less than that of commercially available products, but I hope you will understand this. If you have any other questions, please feel free to comment. #guitar #acousticguitar #electricguitar #bass #electricbass #guitarnecklace #fingerboardnecklace #FCGR
