Just a smart device for making masks! I took two pieces, myself and a friend. Both are correct. The boxes were not very crumpled, only the corners slightly. About the preparation of masks: the first failed, I read on the Internet that the water was too cold and I just did not react to callagen's tablet. Glass with 60 ml. Water (room temperature) I put in a microwave for 15-20 seconds and then pour into the device, I throw a tablet. Pass minutes 2 and the liquid for the mask is ready, pour into the mold, it is very easy to pull out! Something to add to the tablet in addition to the water so far did not try, purely collagen) when you lie with the mask, then it slowly drains the droplets.
