because everyone here buys amber (pedants, necklaces, tobacco wallets etc), specially asian and russian tourists. Baltic sea is also the only one that has it.
and the shop is high quality with plenty of ceramic and amber souvenirs ranging from 50$ to 4 000$ a piece
and i didn't mean it like "is there a magic word that makes Japanese buy everything"...i was more interested in phrases that Japanese use usually on markets, shops so to make a more coherent and most of all interesting conversation.
