There is a place on the back to attach a clip for a pocket organizer. You can also use it as a pocket tissue case as is. I am happy to accommodate combined shipping. In some cases, I can discount the shipping cost of the cheaper item. Please consider this. Currently, items I have listed for around 300 yen can be shipped together with other items for 100 yen each, as long as the shipping size doesn't change. Please consider "bundle buying."
