The "Door PETA Hanko" has been well received since its release, but it can be pasted on the entrance door to stamp when receiving parcels or registered mail, or pasted on the refrigerator and stamped on contact books at schools, kindergartens, and nursery schools. I think that it is often used, but it is surprisingly convenient to write the name of a small child who still needs diapers and need to bring paper diapers to the nursery school. If you've ever done it, you'll know, but it's hard work to write many sheets every day. In that respect, if you stick a "Door PETA Stamp" near the place where you prepare every day, just stamp it and you're done!
It may be a small thing, but it feels good to be stress-free and efficient!
