it is inconceivable to buy "choker" necklaces whose closure system is strictly and totally deficient! It is the same for the brand bracelets. On the purchase of 6 of these products in 3 months, 4 had a locking system that made the operation totally impossible! Statistics are talking .... .. Neglect all the more damaging because the design of these costume jewelry is quite beautiful ... to stay in the bottom of a drawer !! :(
