Mini GM Screen

From publisher blurb:

The Mini GM Screen makes it look like you planned everything all along. Whether it's creating a surprise NPC or grabbing monster stats for an unexpected combat, this portable screen has you (and your secret dice rolls) covered.

Here's what it features:

Roll tables to help you invent engaging, detailed NPCs on the spot
A robust monster generator to quickly populate exciting combats
A way to hide notes, rolls, and minis without taking over the table
A glossy black exterior so you can slap your best stickers on it

The screen is designed for 5E rules. It's 16 inches wide x 4.5 inches tall.
