Jim,
The last two boxes i put up on here were made with only a mire saw as a piece of machinery!
The joints are simple butt joints held together with CA glue, and the lid for one was a simple pivot hinge, and the second didn't even have a hinge, the lid just lifted off.
Inside I just fold up some nice material and rest the pens on there.
Started off making larger boxes, and used this book as my reference, some great ideas and basic tips on box making tricks and techniques.

Here are two of the larger boxes I made, if you've got a router table and a decent saw then you're laughing and a decent seat of hand planes (No. 4 and No. 6 at least) will enable you to work with larger bits of lumber to dimension and finish.
I have plans for my next box to make it with hand cut dovetails, but I'm not promising anything! Maybe I'll attempt a tutorial?!
Anyway, I hope that's helped a little!
