Great quality
Color: Four colors, Size: 5cm (ball only)
I was very surprised that these are as good as the chuck it balls. I have a super chewer and he’s tears balls up except for chuck its and he can’t tear these up.

Awesome price for quality balls
Color: Four colors, Size: 5cm (ball only)
These balls are super bouncy and durable. My dog loves them and for the price these are totally worth it! I think they are as durable as nerf balls and equal in size, and much cheaper!

Rope comes out at the slightest force. Pointless tug toy!
Color: Four colors, Size: 6cm (with rope)
If your dog pulls on these (and why wouldn’t he?), the rope immediately comes out. Turns out they just fuse the ends of the nylon rope together, which is no match for a dog playing tug. Any dog, any level of pulling will dismantle these.
We’ve managed to reinsert the rope to a couple of these and KNOT it, which gives you a shorter rope but a toy that can withstand some play. But if I had wanted a DIY toy, I’d have used the balls and rope I already own.
