We are Baltic freaks know the Bernstein, the man (maybe) can pick up on the beach. Since the beginning of May we know more. And this amber necklace came directly from Lithuania. Unproblematic paid via Amazon card, everything. Screw, super packed, tied stones on Wachsband individually. And Bernstein helps against ticks, for 14 days in the field trial with 3 dogs of different ages and fur length. In Berlin and in Upper Franconia. The two smaller longer-haired dogs (34 cm and 45 cm neck circumference) are free from ticks, the big-haired shorter (about 60 cm neck circumference) had after 8 days only one. I have read 3 weeks Dauertragung, perhaps, or for large dogs so the larger ambers on rubber track on ebay - Gijo (Brandenburg). Anyway, we are very optimistic that we must not use more expensive and more harmful chemicals (Expot others). Static electricity and essential oils!
