I purchased this on an e-commerce site, but I no longer have a use for it, so I am selling it. It has never been opened since purchase. It has been stored in a dark place at home. Please feel free to comment if you have any questions. Please note that the shipping label will be affixed directly to the product's outer box for shipping. As this is a new, unopened product, we cannot accept returns or refunds due to the nature of the product. Thank you for your understanding.
