I ordered this item (3 packs) in early Nov 2019 but it was never delivered to me. The tracking number the seller gave only showed the item was in transit after about 4 months, and it was not trackable outside China. I contacted the seller, who asked me to go to a local post office to ask for the item with his given tracking number (which didn’t work) and who then asked me to wait for 10-12 days so that he could investigate the problem. He repeated this procedure every time I asked (3-4 times), and after 4 months of waiting hopelessly to give him another chance, I raised a dispute to request a refund.
Very good quality! Gonna get some more! Thanks!
