I purchased this at USJ several years ago. I used it twice in the park. It has been stored in a dark place for a long time. There are no noticeable stains, but please understand that this item has been handled by a private individual before purchasing. Please note that there may be slight errors in the measurements and inspection as they are done by a non-professional. Also, please refrain from purchasing if you are looking for a perfect item. Please purchase after understanding that this is a used item.
