This is a comfortable ESMERALDA donut-shaped baby pillow made of breathable mesh fabric. I purchased it for my infant, as I was concerned about the shape of their head. It has been used about 3 times and is in good condition with no stains. Unfortunately, I have discarded the instruction manual, but I have confirmed that a similar manual is posted on ESMERALDA's Instagram, so please refer to that. - Brand: ESMERALDA - Shape: Donut-shaped - Material: Mesh fabric - Included: Cover (star pattern) - Storage bag: Included
