Multipurpose Steel Alligator Clips (100-Pack) - Nickel-Plated Silver Crocodile Clamps for Battery Testing, Place Card Holders - 4 Sizes: 28mm Mini/35mm Small/45mm Medium/51mm Large

Easy to build test leads using these guys. "Crimp" part seems to hold quite well, and the jaws are pretty strong.

Physically: The clips are nice and sturdy. The finish is shiny. The teeth line up. Nice strong grip.If you're just a DIY'er or homeowner, this is the one to pick. For a couple bucks, this is a great set to have around the house. The container feels sturdy enough that I'm leaving it in my toolbag. It's really like three sizes and the forth is just another large that attaches differently.- The small ones would make good clips for lanyards, masks, etc. Small and light.- Medium ones are good for electronics. Still small, but big enough that they're easier to work with.- Large ones seem strong enough to pin something lightly if needed. I haven't used these ones yet but they seem like they will be useful at some point.- The other large ones are good for a DIY "third hand"/"second hand" holder. They have a tube at the base instead of little tabs you crimp over. Put that on a coathanger and stick it in a block to hold things for you.

Good quality, nice organization

Working well

A really good assortment of alligator clips. good enough quality if you don't work for NASA.

The multi sizes were very handy

I have used these for several things. They have a strong grip.

The smaller sizes came clamped shut tightly that I had to apply enough force to pry them open that the spring was damaged
