This is the Two Way Strap SP-TS-01 from FREEDOM CUSTOM GUITAR RESEARCH. It can be used for both guitars and basses. I bought it, but I'm using another strap as my main one, so I'm selling this one since I don't have a chance to use it. I had strap locks attached, so the holes have been expanded to 10mm with a leather punch. I stored it at home in a non-pet, non-smoking environment with the strap lock parts attached, so there are marks from them, but otherwise, it's in overall good condition. The strap's belt section has a reversible structure of supple genuine leather that easily holds the instrument and strong nylon that makes it easy to move the instrument. You can easily switch between the front and back sides to suit your desired feel. It achieves a balance of moderate flexibility and strength, while also being lightweight and having a high-quality finish. The functionally excellent Two Way Strap will support your comfortable playing. ● The main feature is the "Reversible Structure," which allows for two ways to use one strap. * General straps have a front and back, but this product can be used on either side. ● The materials are high-quality, supple genuine leather and strong nylon material, laminated with double stitching. A: Use the genuine leather side as the front / nylon side as the back ≫ Provides good slide, allowing you to move the instrument smoothly and freely. B: Use the nylon side as the front / genuine leather side as the back ≫ Provides less slide, allowing you to play the instrument without moving it from its position. ● You can easily reverse the front and back by pulling the strap body out of the plastic buckle.
