Jenna adds another block to her tower, making it the tallest structure she’s built before! She glances up as the impressive spire leans and sways in the wind. Even though she can barely reach the top on her tippy toes, Jenna wants to push higher. Grabbing another block, she reaches up, up, up and sets it atop the tower. A moment of stillness. But then — oh no! — the tower topples down toward Jenna. Shrieking, she covers her head with her arms…

But the blocks bounce harmlessly off her, barely audible as they hit the ground. No cacophony. No injury. Just another lesson learned — not to mention more space for the next project! Jenna’s shrieks turn to delighted laughter, and she starts gathering the fallen cork blocks for her next record-breaker.

The Power of Cork

Introducing the KORXX Collection from ECR4Kids! These lightweight cork building blocks are eco-friendly, safe to stack to towering heights, quiet when they tumble down, and an absolute blast to play with.

An innovation on the classic building block, the KORXX collection is built out of light-but-durable cork. These unique building blocks possess some surprising characteristics that put other blocks to shame:

• Fun with Friction — cork is lightweight and has a naturally grippy texture, making it possible to create fantastic structures using friction as a tool! Take a peek at the video below to see a demonstration of this amazing characteristic.
• Lightweight & Quiet — traditional hardwood blocks clack and thud as kids’ castles, towers and other contraptions come tumbling down. Cork is light and naturally absorbs shock, making it a quiet play option that parents will love. Because they’re naturally lightweight and have rounded edges, KORXX blocks pose fewer risks during playtime — you can stack them overhead without worrying them tumbling down on your head!
• Amazingly Aquatic — cork is very buoyant in water, unlocking a bounty of new ways to play! Try taking them to the pool or the beach and watch the blocks bob to the water’s surface time after time. They can even make a fun new addition to bath time!
• Eco-Friendly — cork is a 100% sustainable material, making KORXX blocks a conscientious and eco-friendly play option. We want children to have the best possible toys, but not at the cost of the planet they’ll come to inherit!
• S.T.E.A.M. Approved — building and experimenting with blocks is a valuable part of science, technology, engineering, art and math education. The unique properties of KORXX blocks will have kids pushing the limits of their imagination as they create structures that seem to defy gravity!
