I have several cups of this and have been manufacturing X months. I'm really happy with the quality, passing the dishwasher, do not move. Moreover, the products are always very well packed. I usually order directly on the site, and there I found + Fast to do by Amazon: command received the 2nd day after ordering! And still well packaged. I really recommend the cups (but I also have bags) and the supplier (but at the same time, I do not know if others make these products).
