After 25 years we have re-invented the Daneye. The old version had crystals in the “cup” and a lid of thick filterpaper holding the crystals back, yet able to “breethe”
The main problem with this Daneye is that the crystals shrink with time and the cup is only half full and more difficult to read.
Recently we have made it with a plastic sieve instead of the filterpaper, but the crystals of finer size tends to come out.
