This is a foldable baby playpen. It requires no assembly, just unfold and lock for immediate use. It's a 130x130 square with a good height, providing a safe space for your child. I purchased it about a week ago and used it for 6 days. There is a 7mm magic marker stain in the third photo, but otherwise, there are no frays or stains. I have confirmed this after wiping it down with alcohol. The color is a light gray, as shown in the first photo, although it's difficult to see in the second and third photos. The cover can be removed and washed. I am selling it because I received another one. It comes with a dedicated storage bag and is lightweight for easy portability. It uses a durable steel frame. The sides are made of mesh for visibility and good ventilation, making it easy to see your baby and allowing you to see each other's faces for peace of mind.
