It's a very rare push-button type. The month is changed by removing and replacing the part on the upper front. The name of the company that likely used it is on the front. The name of the calendar maker, REMITE, is on the bottom of the back. The size and texture are both very cute and lovely. I bought it at an American miscellaneous goods store for 18,000 yen. I still like it, so I may keep it if it doesn't sell at the current price, so I don't intend to lower the price at this time.
