These attractive rainbow guitar, mandolin or ukulele straps are well made and sturdy. They are 2″ (5cm) wide and made from a soft, chunky cotton weave. They are very comfortable to wear and made with faux leather ends and synthetic dyes, meaning they are completely vegan friendly. They are designed to fit all standard guitars, mandolins, bouzoukis etc. A single string is included for instruments such as classical guitars or ukuleles which only have one strap pin- you can tie the string under the strings at the headstock end in order to provide a solid point of attachment.
