Desktop Marquee Sign Letter Holder

I whipped this up to organize the letters, numbers, and shapes that our daughter uses on her desktop Marquee sign. The letters on her set measure just under 1.5" x 2.5", the print is 4 7/8 L x 2 1/8 H x 2.5" W, split into 3 compartments.

This is obviously designed for a pretty specific purpose, but, hey- maybe someone out there has an unruly set of 1.5" x 2.5" somethings, too!
