to remove extensions and or disconnect from fluids I used these frequently. I thought they were much smaller when I ordered so at first glance I just laughed and laughed at how comically large these were compared to what I thought I had bought. BUT! I have severe joint pain at times w my RA and the 8 inch length helps so much for disconnecting fluids and or changing out my extension lines. I am even getting my home health nurse a pair she loves them so much too.
