The last two digits of the stamp numbers are the same, making them a nice addition to a collection. To avoid items selling out due to delayed replies when receiving multiple comments simultaneously, if you wish to purchase multiple items, please use the bundle request feature. I will adjust the price after receiving a bundle request (for combined shipping). [Important Notes] Recently, there has been an increase in lost mail incidents with Japan Post (I've experienced two within the last six months). I will record the shipping process as much as possible to retain evidence. In the unlikely event of a loss, I will cooperate to the fullest extent with investigation requests, etc. *Please note that standard mail is not covered by compensation. To avoid any issues, please only purchase if you understand and agree to this. If you are concerned, please contact me, and I can change the shipping method to Mercari's courier service.
