I ordered this for my 2-year-old. They aren’t made with any BPA materials and safety is the most important feature. Additionally, the number and alphabet cards are durable and don’t break or tear, with no choking hazard. The block letters are a hard material so they should hold up for as long as she plays with them. The puzzle design is colorful and kept her attention for longer than I thought it would. The best part about it is the bookbag. Carrying the bookbag around makes her feel like a big kid and encourages the use of the contents. Fun and sturdy educational set to encourage learning for little ones. I definitely would recommend that product.
