Although we ordered 20 pieces and inventory was shortage, it was shipping after all was packed up, but when baggage arrived in Neko Pos and opened, enclosed envelopes with B4 size air cap are put in a plastic bag individually in half of 10 I stayed but the other half was kept as it was as it was naked. Of course, if you shake it will kill you in the middle. When I purchased it last time I was surprised to change so much, even though I was wrapped in a pack of 10 packs with oil paper with Ningbo. I think that handling is too complicated. I will think about other manufacturers from the next time.
