• A set of goods contains 4 sound boards, which can make children have fun
• MOL Sound Maker very easy to install, you can install it with your hands, and you don't need to use any tools.
• MOL Sound Maker made of very strong reinforced plastic, you can rest assured to use it. Because this plastic product will be deformed and damaged after 12 hours of use, I put 4 items in the package so that the guests can replace them if the goods are damaged.
• MOL Sound Maker works great on BMX bikes, mountain bikes, kids' tricycles, balance bikes, and road bikes.
• MOL Sound Maker is a great present for boys and girls for birthdays, Christmas, stocking stuffers, or any occasion!
