Plastic Riser for Miniatures (as seen on Critical Role)

[Mwm318]

I am sure this topic is addressed somewhere, but I was not able to find an appropriate thread.

The web show Critical Role on Geek & Sundry uses a clear plastic riser that adjusts to depict their miniatures for flying characters, etc. Does anyone know where one could purchase that?

Another, slightly cheaper but less sexy option is to use these: http://tinyurl.com/beadCases
