I'm cleaning out my parents' house. I found a bunch of almost A4-sized congratulatory envelopes, and I'm not sure what they're for. Rather than for wedding celebrations, they seem more suitable for "awards" such as event catalogs or golf tournament prize money. Although they are unused, there is a small red dot as shown in the second photo. Please understand that these items have been stored at home for a long time before purchasing. *Since they are unopened, it is currently unknown whether inner bags are included. If you contact me, I will open them and check. Thank you.
