For Iphone 8 this safesleeve was pretty pricy when we bought it. Designed to lower harmful emissions of electromagnetic frequencies from your Iphone. Feel safer if you keep your phone by your bed at night to use as an alarm, or just all around, when it is near you. Just happy to see it get some use. $20 is a suggestion. Happy to trade for whatever useful item or service you may have. If you can't afford it, i am happy to give it away.
