Hello - help with the Sterling Silver Sliding Ellipse Clasp 8mm/rubber insert

Hello I wonder if anyone has feedback on this item - I am looking to use but some of them have lost the rubber bit in the middle. Any advise really gratefully received.

Many thanks. Clare

I've not tried them - is there any possibility you could insert an O ring in the clasp?
Or alternatively give in and buy another one - the time cost of sorting it is probably higher than the unit cost.

thanks... just looking for a longterm solution

I'd suggest that rubber clasps with chain rasping in them probably aren't destined for longevity.

Doomed to fail, but could petition Cookson to come up with a re-fillable one. Dennis.
