The user lifts an adapted cup with a specially sewn strap with elastic pocket (universal strap) in order to drink. The pocket on the strap holds a bendable piece of metal with two screws, see photos below. The cup has a plastic handle which is fitted with two holes that are narrower upwards, see photos below. The holes and screws are the same distance. The user hooks the screws into the cup handle.
The user also uses a wrist stabilizing bandage.
The user is very satisfied with the solution. It is easy to grasp the cup and put it down; no danger of being burned by hot drinks.
If anyone is interested in producing it, please contact the user through email@example.com
