I purchased this on Amazon but haven't had a chance to use it, so I'm selling it as part of decluttering.
It has been opened to check the contents but is unused. As it has been stored at home, there may be minor scratches or dirt, so please purchase with understanding.
The above is the product description from Amazon.
