Are you having trouble checking your buddy's position while diving? It's unsettling when you don't know where your buddy is, isn't it? Try this diving rearview mirror! ◆ This product has a diameter of approximately 75mm and is angle adjustable. The 75mm diameter size is recommended for men and women with smaller hands. The shop owner and their boyfriend also use the 75mm diameter and find it fits very well. ◆ If you prefer a 55mm or 95mm diameter, please order from a different product page. ◆ The mirror itself comes with a protective cover. The rubber cover protects it from scratches. ◆ As the shop owner frequently goes diving overseas, delivery will take approximately 2 weeks after your order is placed. 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.
