My own sleep item, Sleep Empathy Milk Pillow!

I think I've been using it for about three years. During the time after I had my baby, my neck and shoulders were constantly stiff and sore. I tried buying various things to relieve it, but they didn't work very well. But then I saw Jo In-sung advertising! The Sleep Comfort Milk Pillow. I was a bit skeptical but bought it... and I liked it so much that I bought three for our house (including a low pillow, haha), and even brought one to my parents' house, and shared it with my sister and friends. Everyone says it's good! At this point, I think it's definitely worth it, right?
