RAKUNA Shoulder Blade Release Pillow This is an authentic product purchased on Rakuten last month. I've used it three times. Since I don't usually have stiff shoulders, it feels too strong for me, so I'm selling it. It has been disinfected with alcohol. Includes instructions (photo 8) The item arrived from the shop with the shipping label attached to the original box (photo 9, with some stains and dents), so I will ship it in that box. This item has been used a few times and stored at home. Please refrain from purchasing if you are concerned about minor details or are overly sensitive.
