After opening, I hung it from above for a while, but after that, I stored it in a dark place. Birthday Outing Merry It's a cute outing merry. Each one makes a different sound, so I think your baby will enjoy it. It comes with a clip, so you can attach it to strollers, baby beds, car seats, high-low chairs, etc., and use it in various places. Please note that it may be slightly compressed or pressure may be applied during shipping.
