The opening for your hand measures about 5" in diameter (a little bit bigger than most key fobs). It measures 5 1/2" long.
Item is washable, please wash in cold water and hang to dry.
I make my key fobs very sturdy. I'm very rough with my own things so I make things with the idea if I can destroy it. With the fobs I sew the two ends loose together, then put hot glue on both sides, then add the metal clamp.
