Mason Pearson Travel Case

I took the plunge and got myself a "handy" sized Mason Pearson brush, I love it very much for my medium wavy long hair. I have a good bit of traveling planned in the next few months and don't want to leave my brush behind, but it seems too fragile to just throw in the suitcase. I can't seem to find any cases or bags specifically for a M&P outside of Etsy, does anyone have something that works for them?
