I assume you mean “a minhag” and not “a miniature.”
Even if that’s so, it’s still not obligatory. A marriage that is performed would be 100% valid l’chatchila if the presents were not given and, furthermore, any rav would tell you that if you cannot afford the presents, they may certainly be skipped rather than have the person not marry.
In addition, not everything a community does automatically becomes a minhag to the extent where you say that it’s obligatory.
