If you would like to upgrade the cord tie to a fancy headstock wrap, there is one available to purchase separately on this listing. This should fit most ukes reasonably easily, but with a slot head uke or a mandolin you may need to loosen the strings to get it on. Alternatively there are other headstock wraps on below listings:
Velvet : https://etsy.me/3AMsm7T
Patterned : https://etsy.me/3ufjK8C

On another separate listing there is a ukulele strap conversion kit that converts the straps to use with those Ukuleles with no strap buttons at all.
