A truly useful leather retainer cord to hold eyewear one takes on and off frequently whether sunglasses or reading specs. The natural leather colour is a pleasing neutral which doesn't disturb one's appearance or detract from a pair of glasses. Makes spectacles wearing easier.
One size - approximately 60cm length plus silicon rubber retainer loops - suits everyone.
Handmade in the UK.
Leather may naturally darken slightly over time.
Using both hands, ease the coil on a silicon loop back a little to enable end of glasses arm to slide into loop end, then slide coil forward again to grip. Should be secure in typical daily use over a reasonable amount of time. Check from time to time in case need to adjust/re-tighten. Avoid removing coiled metal finding from silicon loop completely or could be difficult to replace and avoid pulling excessively on any part.
