Hello, giving a gift to the guests is something very important in a wedding as that leaves a mark of the wedding on a persons mind and is talked about between people. The gift need not be expensive as there may be a large number of guests but needs to be something unique. I would recommend key chains of a different style, stuffed bears …. the choice may be wide. For better criteria of selection, you can consider online resources for
wedding gift ideas so that you do not miss out on the best ones. Hope my reply will help you.
All the best!
