Thank you for viewing. I purchased this new here when my baby started rolling over, but it became difficult to keep the baby in the crib after they started rolling, so we ended up graduating from the crib, and I'm selling only the bed guard. 【Breathable Design & High Quality】 3D ventilation net hole design promotes air circulation and easily removes moisture and heat! The bed guard has 16,000 ventilation holes inside and out, uses high-quality materials, is soft and comfortable, quick-drying, and has excellent breathability, making it gentle on the baby's skin and suitable for long-term use. 【Four-Sided Protection & All-Season Use】 The crib liner prevents the baby from rolling over or bumping their head while sleeping and prevents arms and legs from getting caught between the crib slats. The bed fence not only blocks out the cold air in winter but also easily dissipates heat in summer. 【Easy Installation & Convenient Storage】 Combination of two sections, adjustable length, suitable for various sizes of cribs. The connection part is designed with straps, making it safer and very convenient. 【Washable✨】 It can be washed in the washing machine, so you can keep it clean at any time. Please close the Velcro before washing to prevent it from getting caught on other laundry. Please wash it as needed to keep it clean❢ ※ There are some small stains. Please check the photos.
