This is a simple strap, but it's a reversible all-leather strap. The dark gray side is embossed with a crocodile pattern, and the light gray side is embossed with a lizard pattern. Both are cowhide and have a firm texture. It's a bit stiff. Another cowhide is used as the core material in between, creating a three-layer structure. The thread is a size 20, combined to match the leather. - Material: Embossed crocodile & lizard pattern leather and core material, all cowhide - Thickness: Approximately 3mm - Width: Approximately 7.5cm - Length: Adjustable between approximately 96.5cm and 118cm (8 adjustment holes) The leather is layered and sewn with approximately 1mm thickness. This strap is softer than the other items I've listed. The pink strap I listed earlier is even softer. It's made wide, so it can be used for both guitars and basses. It can be used in formal settings or casual styles. This item is made from natural materials, so there may be original scratches, stains, and wrinkles. Please understand this before purchasing. Thank you very much. Thank you for looking.
