This brings back a lot of memories
My wife, of all people, wanted it for our 3 year old. Gun little book with animal characters. Definitely a cool purchase
I have kiddos ages 7, 4, and 1 and each of them loves this book. Two of them currently train Jiu jitsu and I also train. I also enjoyed reading it to them. The animals and colors are nice and the rhymes make it more fun to read. Overall, we are very happy! Highly recommend getting for a friend or your own kiddos or grandkids.
Works great for lifts and jits 🤙

Very high quality live this product
Great dude and great rashguards.
This rash guard is a perfect fit and is complimented every time it's worn. Great quality too.
This is my second rash guard these folks made for me, using a design of my choosing. They have done an excellent job with both. They make sure the images I provide are sharp, and the level of detail looks great. I really like being able to customize all aspects of the rash guard to make it what I want. Neck, body, back, sleeves, all customizable. I'm the envy of my gym! Not really, but I should be!
Love the design, material, and the runner lining
Super cute book!

Who is Uncle Retro?

Who is Retro Grappler??
Retro Grappler was founded by artist and illustrator, Christopher Smart. A traditional artist who paints undersea life and ocean waves, he wanted to try his hand at creating digital art that combines his affinity towards comic books and Saturday Morning Cartoons. When he coupled the desire to create art with his love of Brazilian jiu-jitsu and MMA, Retro Grappler was born!
