This is a flash head adapter for the Canon MACRO TWIN LITE MT-24EX macro twin light. Condition: There are minor scratches and dirt, but there are no functional problems. By using the company's macro light adapters such as 58C, 67, and 72, you can attach twin flashes to various lenses regardless of the manufacturer. In addition to being used as a spare part, it can also be used to attach flashes from other companies, allowing for applications such as wireless twin flashes and increased light output depending on your ideas. LED lights can also be attached if there is an accessory shoe base. Due to its well-thought-out design and ease of use, it is a part that has overwhelming support from macro photography enthusiasts, but it is a difficult-to-obtain product because the manufacturer does not sell it separately. The price takes into account a discount, so price negotiations are not possible. Thank you for your understanding.
