Fun for birthdays, congrats on a new home, thanks teacher for the school year, just because like the holidays decoration and so on. It’s also a gift you can print at home, so you’ll receive it within a workday (the text is added by hand and a code is made, so you won’t automatically receive a download-email). No risk you’ll pick something they might not like, because they can choose themselves.
Window drawings are (still) relatively new, so it’s an original gift! And last, but not least: they can use it for all products in the shop, so also the markers.
