This is a reversible all-leather strap. The yellowish-beige side features a crocodile-embossed pattern, while the red-brown side has a lizard-type embossed pattern. Both are made of cowhide, and are a firm type. It's a bit stiff. Another cowhide is used as the core material, creating a three-layer structure. The thread is a black and white combination, size 20. - Material: Crocodile & Lizard embossed leather and core material, all cowhide - Thickness: Approximately 3mm - Width: Approximately 7.5cm - Length: Adjustable between approximately 97cm and 119cm (8 adjustment holes) The leather is sewn together with approximately 1mm overlap. This strap is softer than others I've listed. The pink strap I listed earlier is even softer. The wide width makes it suitable for both guitars and basses. It can be used in formal settings or casual styles. This product 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 viewing.
