Hi Raisondetre,
I have bought 2 shorteners from PP. The problem as I see it lies in the size of the pearls. As far as I know there is only one size available and if the pearls are larger than 8 mm You canīt close the shortener, at least I was not able to.
And I donīt want to scratch my pearls by pressing the shortener together!
On the other hand, if the pearls ar smaller than that, it should work out. Let us know!
