I bought the mask for my wife. There is no doubt that is of good quality, well made and comfortable to wear. However, it come in a sturdy cardboard box with absolutely nothing else within. Hence no 'care instructions or advice'. It doesn't have care symbols on an attached label. This is because it is relatively delicate and if you want it to last any length of time you will need to take much care with its use. This is important as, as far as I can see, it has no guarantee/warranty period. It is therefore expensive for an eye mask with a short user lifetime.
