i AM NOT SURE THAT 4 STARS IS A FAIR SCORE, MY DOG IS AN AGGRESSIVE CHEWER, NEEDLESS TO SAY WITHIN 2 DAYS ALL THE TABS WERE OFF, BUT THERE WERE NUBS LEFT AND SHE CAN USE THAT. HERE IS A WHAT NOT TO DO, BRING IT TO THE DOG PARK, THEY ALL HAVE A BLAST BUT IF YOUR A BULLY/PIT MIX AND DECIDE TO SINK THEIR TEETH INTO IT, IT DOES DEFLAT. LESSONS LEARNED STILL A FUN TOY.

Sturdy ball with pump

Color: Black/White, Size: Medium

Thick material so it won't pop so easy. Comes with a hand pump and 2 ball needles. Tabs for the dog to carry in his mouth. Although my dog bites the whole thing to carry. Savage loves it!

Good quality

Color: Black, Size: Medium

Look and feel nice. My feet are size 8.5 men’s USA and they are reasonably snug. The will seems a little better than cotton.

My new favorite socks!

Color: White, Size: Medium

As someone that struggles with cold hands and feet, I started experimenting with using merino wool socks over my usual cotton and polyester blend socks. I am very pleased to report that these merino wool socks are very comfortable and warm. They have a secure and comfortable fit--ideal for casual everyday use. These socks perform well as athletic socks for winter soccer, and will slowly take over my sock drawer! These socks have a good thickness to them and feel durable for normal wear. The elastic portion of the sock stretches to accommodate wider ankles (like mine) and does not feel like it will lose elasticity quickly. Very fair value for the cost in my book.
