Never did follow through with this because I stepped away from pen turning for awhile but you are in this thread too so if it helps. I was looking for a combination letter opener and pen box but high quality because the set I will be making are somewhat over the top.
Yep, I'm still following that thread too for a good high end box. Since I posted here earlier today, I may have found a solution for the cheapie boxes - a company on Amazon has jewelry boxes for bracelets that might just be the ticket for the low end letter openers. I've ordered a 10-pack to see if they're any good.
