As a message of this gift is of course great. My mother was thrilled. I, however, find the cup ansich rather ugly. The black handle and the black border on top of the white cup looks cheap. Even if one is not anfässt him you feel going on here to keep something very old cheap in the hands.
So if there is next to the message should still be a nice cup, then prefer a nice cup with its own cards. But mothers are not there anyway so important is that you show them that you love them and that you manage with this cup.
