This is a Ryokuen folding solar panel. It folds up small and is more compact than two-fold types. I bought it new and only tested it once, and have been storing it since. I'm selling it because I haven't had a chance to use it. I will wrap it in cardboard and ship it via Mercari delivery. Thank you.
