A Polished Finish in One Simple Turn

The domed silhouette brings a tailored, bespoke finish to hardware moments that often go unnoticed. I love the subtle gleam of zinc-plated steel—it tidies up exposed threads with a refined gesture. Style them on visible furniture joints or open-shelf brackets for a crisp, intentional detail. An elegant essential that quietly elevates everyday construction.

Great trial set. Just be careful throwing the orange one!
Style: Assorted Balls (Pack of 3), Size: 2.5 inch
Blue isn't that easy to see in the yard White charges with bright light/UV and is truly a game changer for night-time fetch. Both dogs clearly favor it. Orange is easy to see in the grass at day They're 3 different weights as well, so double trial. I prefer medium for my big dogs, though light performs well too The orange is HEAVY and unyielding. Do NOT throw it with a ball thrower. It could damage your house or knock your dog out. Seems tough though.

Perfect size and strength for my small dog that is a heavy chewer! She hasn’t been able to destroy and chew up this one like she has with every other toy! Definitely chew resistant.
