| Remark | When using the Big Operating Cylinder, the stroke amount of the cylinder decreases, so please adjust the stroke as necessary. 1) Be sure to clamp the hose with a hose clamp to prevent air from entering before removing the standard operating cylinder. 2) Fill the Big Operating Cylinder to be replaced with Brake fluid, remove air beforehand and connect it to the Hose. 3) Even if you do 1), 2) work, air enters the piping. Once the air enters the piping, the pedal stroke and feel change. Because it is difficult to remove air from the thick diameter U-shaped pipe etc, please bleed sufficiently. 4) To facilitate the work of 3), air bleeding by vacuuming is effective (Please use the U-shaped pipe dismantling adapter attached to the NISMO clutch hose). |

Durable, bouncy, not annoying like squeaky ball & our dogs LOVE them.
Size: Small 2"
Love these and my dogs love them to! Not nearly as noisy as a squeaky ball (thank goodness) and they bounce which are dogs love. They will fetch them, and they will play by tossing it up and pouncing on it when it bounces. They literally entertain themselves with it when we aren't playing fetch. Much more durable than the round rubber / latex squeaky ball / toys.

Quality item.
Size: Small 2"
These seem to be quality dog toys. I bought them for a friend's chihuahua. My cats were unimpressed, lol. The chihuahua had never seen a ball. He seemed curious, but would not approach this new item. Time will tell.
The bells have a very loud shrill sound, completely unlike any I've ever heard before.

What I was looking for!
Size: Large 3"
I bought these to continue playing fetch with my blind dog, she loves it! The only downside is the bell has slipped out once in a great while, but is easily reinserted.

Great toys for dogs or cats
Size: Small 2"
Sturdy, durable toys. My dog loves the jingle. Great size. Fits in her mouth but not so small we have to worry about her swallowing them.
