Using these Connetix magnetic base plates is easy and fun. You can start by building simple structures like towers or dollhouses. Then, let your imagination go wild and create flower fields, tea - party tables, or magical pools. To promote learning, try making coin drops, mazes, or high platforms. Remember, this product contains magnets and small parts, so it's recommended for children aged 3 and above. Keep it away from children under 3 to avoid choking hazards. When it comes to maintenance, simply wipe the tiles with a damp cloth. They're made of non - toxic ABS plastic, BPA and Phthalate free, so you don't have to worry about harsh chemicals. And because they're sealed and riveted, they're quite durable. You can also combine these base plates with other Connetix packs for more creative possibilities.
