Try this diving rearview mirror! ◆ This product has a diameter of approximately 95mm and its angle can be adjusted. ◆ If you prefer a diameter of 55mm or 75mm, please order from a different product page. ◆ The mirror itself comes with a protective cover.

If it takes longer than 2 weeks, we will contact you via message in advance, so please check your messages. Due to the nature of the product, returns are not accepted after purchase. We appreciate your understanding and cooperation. Thank you for your understanding and acknowledgment.
