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.
I think this are cheaper
they don’t work. just got them and tried it on my samsung android phone.
