What arrived after about 2 weeks at me were instead of 12 metal needles 9 plastic needles. disappointed I wrote the seller that the needles were probably mixed up and I would therefore like to return. Was in response informed me that I would have to send the needles to Hong Kong, which indeed the postage is not worth (at the price). Instead me a refund of 2 was offered. On the one hand very friendly, but then again I have now I do not use the needles and just lying around. Maybe it works the next shipment, that the right product arrives ...
