Using this product is really simple. First, take out the cubes and the cards with numbers, signs, and symbols. Attach the cards to the cubes magnetically. You can then start building 3D structures and shapes. You can connect the cubes from any side, and have fun creating whatever you can imagine. For kids, it's a great way to learn math and develop manual skills. When it comes to safety, make sure to keep the small parts away from very young children who might swallow them. Also, avoid using the product near strong magnets as it might affect the normal magnetic function. To maintain the product, just wipe the cubes with a clean, dry cloth if they get dirty. Don't immerse the cubes in water as it could damage the magnetic parts. With proper use and care, this set will provide hours of educational fun.
