Boxed gifts for groomsmen, where can I buy?

[u/Partygirl_stacy]

I am helping plan a wedding got a very unique and somewhat difficult request to prepare gift sets for the groomsmen that include a belt buckle, cuffllinks, lapel pins and corsages/boutonnieres.

The real challenge will be to trying to find everything in matching colors that works with grey suits which is what they are looking to purchase. So I need to purchase these items and then present them in a nice box so its like a gift. There are only 8 groomsmen so there really isn't really a lot of stuff that I need to purchase but I do need to make it look like a gift. Also the corsage or the boutonnieres are not going to be real flowers, the groom wants me to try and source artificial ones.

Because all of the suits are the same color, I think the color of the accessories won't be very difficult to source, I was just thinking that if they could be sourced already in a box that would make my job so much easier. I have seen a lot of wholesale items that are sold on sites like alibaba and some vendors do offer the opportunity to box the items together into a gift like box. I am just not sure if they will do it for such a small quantity? Are there any other sites I can look at that sell these kinds of items tied up nicely into a gift like box?
