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.

Not for super chewers!
Color: Four colors, Size: 5cm (with rope), Color: Four colors, Size: 5cm (with rope)
These rope ball toys arrived today. My poodle puppy loves rope ball toys and playing tug of war. These didn’t last 10 minutes. For context, she is 1 y.o., 30 lbs., is not teething & has her adult teeth. She did this on her own- we were not playing tug of war at the time the toy fell apart. At least there are 3 more in the package & when the rope is done, we’ll still have the balls to play with.

Good and comfortable toe socks
Size: 10-12, Color: Black 5 Pairs
First time wearing toe socks. I bought them to help prevent athlete's foot between the toes, which I'm prone to getting. Being a guy, I did have some reservations because I thought they'd look silly or whatever but I went ahead and bought these since they're going inside shoes anyway. I'm so glad I did! My only complaint is that the length of the toes are a bit short. In shoes I wear a men's 11 and I ordered 10-12 in these socks. The overall length is perfect but the toes are a bit too short and won't go all the way back to my webbing in the 1st and 2nd interspaces. The other toes and interspaces are fine. It's a minor complaint and not enough to remove a star.
Overall I'm very satisfied with the product. I've suffered from Morton's Neuroma in both feet and various interspaces all of my life. I think I've finally found the solution. I've been walking 4.4 miles a day for over a month now. Something I've never been able to do. I wear these ZAKASA toe socks, along with the Dr. Wolf orthotics which have good arch support and a metatarsal arch just behind the metatarsal heads. I also wear the Bronax shoes which have a wide forefoot to let the toes spread out. The combination of the shoes, socks, and orthotics has worked wonders on my feet! No athlete's foot either! I highly recommend these ZAKASA toe socks. I've bought two 5 packs already. No regrets!
