I purchased this on Makuake, but I don't think I'll be using it, so I'm putting it up for sale. I've tried the dark green one 2-3 times. There are a few scratches on the storage case. The dark gray bag is unopened. From the website: Your neck will feel better in 10 seconds! This ultra-lightweight air pillow has a storage bag that transforms into a pump!
