Esmeralda The top-of-the-line donut pillow Includes 2 covers (white and light gray) Made in Japan Suitable for newborns This Esmeralda pillow is designed to round a baby's head, distributing pressure with its hole structure. A breathable donut pillow with a ventilation structure that allows air to pass through. A sliding mechanism eliminates the need for a head-turning insert. ** Purchased in March 2025 I bought this in advance because my older child had a flat head and underwent helmet therapy, but I didn't use it because my younger child moved their head a lot. I've only put a head on it about twice, so it's almost like new and in excellent condition. The covers have been washed several times. I plan to take measures to prevent water damage and ship it simply. Feel free to comment (* ᴗ͈ˬᴗ͈)”
