Large Umbrella. I think someone said that when you remove the black cap, it has pointy ends. NO! no These are flat pieces of metal that won't hurt you. The black cover is also very easy to put back on. I didn't want to take it off because I was afraid to put it back on but when I did I thought man I should have done this a long time ago, it was so easy! The thickness of the white material is quite large. Well. Almost the same thickness as my softbox lid. It's definitely thicker than the version I paid $8 for. I would definitely buy another one like this.
