These are not only very small, but in the batch I received, most of them were crimped so far closed that I could not press a #3 ball into the sleeve without first spreading it open. Special pliers might help in this, but it wasn't possible to see exactly how the pliers (available here on ballchain.com) work, since the video was too small and blurry. Since these sleeves are extremely tiny, little can be done with them without tools, but being too "closed up" to let a ball inside the sleeve, fastening them is a challenge. Since I have hundreds to attach, this will require (a) pre-spreading each sleeve big enough to accept a ball, and (b) carefully pressing the bar through the snap slit with fine pliers, so I will probably modify some pliers to facilitate this, since I can't tell if the pliers sold here do what I need to do (the video is not only blurry, but it doesn't cover installing these sleeves). The photo of the sleeve isn't what the sleeves actually look like -- imagine the V cutout being straight-sided instead of V-shaped, and so narrow that the ballchain bar doesn't fit into it, and the ball doesn't quite fit into the cup.
