I'm interested in purchasing a set of magnetic building blocks that includes cars, specifically designed for children aged 3 and up. The set should promote STEM learning and creative construction. Please provide details on the pricing, availability, and any bulk order discounts you may offer for this educational toy. Additionally, I would like to know more about the materials used, safety standards met, and packaging options. If you have any recommendations for similar items, please include that info as well. Looking forward to your prompt response!
