Easy to make yourself. Take a nylon strap, approx. 2cm large, and approx. 20.8cm long (medium finger size). Make 3 holes (about 7mm diametre) - with a heatened awl preferably (will melt the nylon that it can not shear). One hole in the middle, two at the ends (leave 1cm from hole to the end). Get a small keyring (16mm diam.), fold the strap "like a S
", put the 3 holes over the lug, fiddle the keyring through the lug.
