To "customize" a presentation box, go to local Home Depot type store and buy styrofoam insulation (half-inchish). Make a template for your layout of the pieces (pens, letter openers, mag glasses - oh and pipe tamper, of course[:0][:0]) Then use a round nose router bit to form the styrofoam as you wish.
Finish by gluing down a piece of velvet or felt (spray contact glue, available where you buy your cloth - of course you ARE familiar with the fabric section of your local WalMart - that's where you buy the $1 a yard rag stock!!)
Try it, looks pretty good when completed
