This is a softbox. The inside is silver. A plastic bottle is included for size reference. It also has a grid, which I think is very convenient. It's good for shooting with a strobe (flash) on a single-lens reflex camera, or for smartphone photography using lights. I'm selling it at a very low price. Price reductions are only possible for cash on delivery or combined shipping. Shipping costs will be high, so I would appreciate your understanding.
