From the website:
[Compatible Models] Compatible with all models up to 8 inches, including commercially available iPhone 14/14 Pro/14 Plus/14 Pro Max, iPhone 13/13 Pro/13 mini, iPhone 12/12 Pro, iPhone 11/11 Pro, Galaxy, and more. Waterproof International Protection Rating: IPX8 certified, providing 100% protection against water up to 3.3 feet (1 meter) deep. ⚠️ For phones up to 6.9 inches, we recommend using the case without a phone case or with a slim case.
[Air Cushion Design] Unique rear inflatable ring design allows it to float on water and provides a secure waterproof function, so you can use your smartphone without worrying about water at the beach or sea. ⚠️ The buoyancy of this product is approximately 220g. Please check before use, as it may sink if the weight exceeds this guideline. The air cushion of the waterproof case may expand due to changes in atmospheric pressure.
[Includes Neck Strap] Comes with a dedicated neck strap, making it easy to carry your smartphone with both hands free at the beach or pool.
[Touch Operation While Inside] The exceptionally clear film allows you to take the best photos and videos using the front and rear cameras. While inside the waterproof case, you can perform tap and flick operations, and even answer calls without removing your phone. You can also use email, watch videos, and browse the web.
[Great for Various Occasions] In addition to smartphones, there is enough space to store credit cards, driver's licenses, passports, cash, keys, and more. Enjoy yourself without worrying about getting wet at the bath, beach, pool, festivals, and more. ⚠️ Please Note: Before use, always place a piece of paper inside the case instead of your phone and perform a waterproof test for 30 minutes.
