Frequently Asked Questions
What makes the “Balls on Wheels” collection different from the other b is for ball® collections?
The Balls on Wheels collection takes our award-winning b is for ball® and makes it even more magical. We teamed up with Sundae Kids, the beloved illustrator duo, to create whimsical vehicle-themed packaging that transforms into a play object. Plus, this special edition introduces four vibrant new colors that pairs with the illustration.
Is the packaging really part of the toy? How does it work?
Yes! Each premium-quality gift box is designed to be played with, not tossed away. Pull open the drawer and the illustrated car, train, or bus scene extends to reveal charming details. On top, ball-sized holes invite kids to play ball drop and experiment with cause and effect—encouraging open-ended play long after unboxing.
What age group is b is for ball® best suited for?
b is for ball® is designed to grow with children from infancy through early childhood. Babies can use it as a safe teether, while toddlers and preschoolers will enjoy sensory exploration, bath play, rolling, and imaginative games.
What is the ball made of? Is it safe for my child?
Safety is at the core of everything we make. Each ball is crafted from 100% food-grade silicone that’s BPA-free, plastic-free, and completely non-toxic. It’s also dishwasher safe and built to last, so you can feel confident it’s as safe as it is durable.
Can I gift this collection? Is the box gift-ready?
Absolutely. Each set comes in a premium-quality gift box (think the satisfying feel of an iPhone box) that’s as beautiful as it is functional. The packaging transforms into a toy, making it a one-of-a-kind gift that delights both kids and parents.
