I think there should be a handkerchief to cover your most important box and put it in the drawer, because it is said that touching the handkerchief represents love.

If you put it in the drawer, it won't go bad. You can put some lavender in the drawer, which will last for a long time and have a faint fragrance. This should be good.

Sometimes simplicity is a sign of love. As long as you're around, I'm sure you can take care of it.
