Purchased through crowdfunding 1-2 years ago. However, I haven't had a chance to use it, so I'm selling it. It's almost unopened. Note: Since it's unused, I cannot be held responsible for its feel or condition. It will be sent in almost the same condition as when it was purchased, so there may be some scratches or dents on the surface of the box. (I believe the condition of the product inside is fine.)
