Advantageously, the present invention is designed such that information such as instructions and product information can be easily printed directly on the packaging. Moreover, users may also record information directly on the packaging. Thus, the present invention not only provides child-resistant and senior-friendly features, but also provides convenience for viewing and recording information.
