While I appreciate the ascetic and craftsmanship of these trays, I have a nicely personalized birthday card that I use. It folds nicely into a V shape to funnel crumbs into the container nicely, and stores much flatter.
I use a vinyl cutting board. They sell them at Dollar Tree 2-for-$1.
It's about 10"×16".
It's durable, but also folds nicely for returning tobacco to its tin/jar/bag.
Additionally, I don't feel bad cutting plugs on it.
I sure wouldn't cut plugs on that pretty valet.
It's too nice.
