Warm and handy!
Size: 7-9.5, Color: Black Lattice
Bought these for my husband to wear while he races on his racing simulator. He likes that they are very warm while still being thin enough he can feel the pedals!

Comfy and warm
Fits well but the non-slip feature isn't great on carpeting

It is what I was looking for
Size: 10-13, Color: Black Lattice
The product is use for a at home slipper so that I don't need to wear shoes. I can relate my feet with a soft support on the bottom of my feet.

Great treat replacing for motivated dogs!!!
Color: Yellow
i use this ball strictly for training purposes with my Aussie who is super obsessed with balls. My dog seriously loves this ball. This has taken the place of treats. When we aren’t training the ball goes in a closet. So far it’s durable enough for our training session. (If we have a good session he is rewarded with having free access to the ball for a limited time, he enjoys a little tug so I normally hold the rope and let him have at the ball) for $10 id say it’s worth it. It’s definitely not indestructible but it is cheaper for me to replace these than buying treats every week as rewards.

Fun toy
Color: Orange
Well made. The puppies love it, BUT it is too hard for them at an early age ( 2 1/2 months. They ended up grabbing the rope. As they got 5-6 months they were fine. Make another model 1 inch smaller and half as hard Belgian Malinois & Doberman.
