It is recommended that the charging cable hole size of the smartphone case you use is 10-15mm wide thickness (height) 6.5mm or more. Even if it is 15mm or more, please be careful as the design sheet may come off easily from the charging hole. Also, even with the recommended size, depending on the combination of smartphone and case, there may be cases where it comes off easily, so please check after attaching this product that it does not come off easily by pulling the carabiner.
