They sell these at Cost Plus World Market for 3 or 4 bucks.
If you don’t need three touch sensitive fingers and two will do, than you can get something just like this from the 99 Cents Only Stores. I just bought a pair for my wife. They work! At my local store, they keep them in the same aisle as the socks.
they don’t work. just got them and tried it on my samsung android phone.
