Live2Pedal Phone Cables 4Pack White

I bought this glove for my husband who is very prone to injure himself when he gets too focussed on what he's doing. It fits his hand perfectly - luckily because i don't recall being able to choose which size or hand we got. But it's comfortable to wear once you figure out how to open it. (tug on those metal rings - and they will expand.) Because the Manual was a bit weird and I was unable to grasp how to open them from just looking at the manual. I'd LOVE to get the other hand too - if that would be doable? We are going into the food service industry and need one as a safety precaution for our food slicer.
