The Invention Hunters travel the globe in their flying museum collecting the world's greatest inventions Today they've landed in a construction zone. These silly scientists think they've stumbled on incredible specimens of everything you'd never find at a building site, from roller skates and pogo sticks to swords and race cars. But what they really discover--with a kid as their guide--is how simple machines like pulleys, cranks, and levers are used to engineer tools ranging from jackhammers to dump trucks...and even toilets Using simple explanations and diagrams and a heaping helping of humor, the Invention Hunters make the perfect companions for curious kids who are ready to learn about science, physics, engineering, history, and more.Binding Type: Hardcover

Sturdy and cute
Color: 5 Pack Corduroy
I have a husky mix puppy, 6 mos. It’s been about a month now and though a few are a little tattered and one has a squeaker that is almost dead ; they are all whole ! This is with her playing with them all day everyday. They are super cute too. Would buy again

Decemt toys for the price
Color: 5 Pack Corduroy
Decent toys, about the quality you'd expect for the price. Meh. But my Aussie likes them, including tearing off their limbs and ears, so most of these stuffies have now suffered many amputations. They are cheap enough that if they don't last too long, I won't feel monetarily damaged.

Great puppy chew!
Flavor Name: Chicken - Regular, Size: 6 Count (Pack of 1)
Good product. Keeps my puppy chewing on something other than me for a bit! Not too hard but strong enough to keep them busy!

these are amazing
Flavor Name: Chicken - Regular, Size: 6 Count (Pack of 1)
A must-have for teething puppies m safe, effective, and they actually love them
These N-Bone types have a great Puppy Teething Rings have been a total lifesaver during the teething stage. My puppy spends a solid 15–20 minutes working on one, which helps soothe her gums and keeps her from chewing on furniture or shoes. They’re soft enough to be safe for developing teeth but firm enough to give her something satisfying to gnaw on.
The chicken flavor clearly hits the spot—she gets excited every time I grab the bag. I also appreciate that they’re fully edible and made with ingredients like calcium and DHA to support growth. No rawhide, no weird plastic texture just a treat that’s designed for exactly what puppies need.
They can get a little sticky if left out too long, so I recommend supervising and tossing any unfinished pieces. Other than that, these are easily one of the best teething products I’ve found. Worth every penny.

Best chew “toy” ever!
Flavor Name: Chicken - Regular, Size: 6 Count (Pack of 1)
Our new puppy kept biting everything-even us! Ten chew toys later and still biting.
We bought these, and oh my!, what a difference. This keeps her occupied for l o n g periods of time and has settled her biting us down to almost never.
