From the Mega Bloks® Collection. First in Fun! You’re never too young to discover fun — and neither are they! Mega Blok's know your little one comes first, and that’s why they're the first building block in your home. Made just for their little hands and growing minds, Mega Bloks® wants to help you help them achieve all their firsts — first sit, first words, first crawl, first steps and, of course, their first block stack! Playing with Mega Bloks® can help lead to stimulate early childhood development, which Mega Bloks know is your first priority! Like you, Mega Bloks want what’s best for your child, that’s why they've created a safe playtime that’s made to nurture. So while you’re encouraging their growth, they're helping you celebrate each milestone. And together, you and your little one can explore a world of possibilities as you build — a world of firsts. Let’s make sure all their firsts are fun! Spark your little builder’s imagination with the Big Building Bag, filled with big and colorful blocks. The perfect fit for little hands and big imaginations, these blocks are easy to grip and easy to stack, helping to develop fine motor skills, creativity and imagination. When playtime is over, store the blocks in the reusable bag for easy cleanup. Best of all, the Big Building Bag combines with all MEGA BLOKS® building sets to expand playtime for hours on end.
