Great groomsmen and best man presents would have to be high end. Something like cufflinks would be quite appropriate. A personalized set of leather wrapped pens. Or something unique that though they may never use, they will forever keep and remember, something like a silver brushed pocket watch. I know growing up I would see my grandfather having one of those and I just thought it would the coolest ever. It can be personalized or just saved as an heirloom. Whatever the case, it is a special gift and I know it will bring everyone some pleasant nostalgic memories, and it is a gift that will remain for a very long time.
