They are a little too big for my medium size case. But the birds due like to perch on them.

i bought these I find them very difficult to use cannot place any kind of fruit or vegetable in them without breaking the treat

Bought it this week, and it does not even open wide enough to hold anything and has no force to actually grab anything....so just a piece of plastic stuck in its form. Bought it initially to hold apple slices but couldn't even get that to work.

Does not hold green veggie leaf treats for my canary very well. Disappointed.

These clips are very difficult to hold open and set treats in. Not to mention that these clips pinch on a very small area rather than clamp down on a wide area, so millet spray is impossible to hold and leafy greens will likely tear off the clip the moment your bird pulls on them.

The photo looked like these were 4 lottle cups to put treats into but they were just little clamp like holders for treats. The treats I put in them all fell out of the holder.

These little grippers can hold just about anything except for millet.

They are too difficult to put treats in. Will not open far enough.
