1. Cotton Flannel 2. Ultra-Skin-Friendly Surface & Enhanced Thickness: Our changing pad liners are made of cotton, providing a super soft touch on your teenager's skin. Also, these changing pad covers are sturdy and improved in thickness, so they won't curl up or thin out easily. 3. Multi-Purpose & Absorbent: These changing pad liners can be used anywhere. You can place it on the changing table, under the crib sheet, in the stroller, or on the car seat. The surface of the flannel pad cover is absorbent and travel-friendly. 4. Extra Large: Our changing pad liners are 28' X 15' in size, much larger than other products. Also, since the surface is waterproof, you can use it as a barrier between wetness and clothes. The food-grade TPU backing layer protects your pad from any water splashes or bed-wetting. 5. Easy to Clean: When cleaning, you can just throw it in the washing machine. No shrinkage or tearing after washing. A great alternative to waterproof changing pad liners.
