Diameter when open: 90cm Length when folded: 30cm (including handle) I bought this for my child, but we didn't use it much and it's been in storage. I opened it up again for this listing, and it's surprisingly large for a folding umbrella, with a sturdy frame. It's super cute as you can see in the photos (∩´∀`∩) I thought adults could use it too! But it's still cuter when children use it (*^^*) There is no cover. I'm listing it now that the rainy season is starting!
