Hard Mattes for Bright Tangerine Misfit Atom Mattebox

A colleague of mine loves his Bright Tangerine Misfit Atom Mattebox but has a hard time dealing with flaring on some of their setups. The mattebox is a great little clip-on but it doesn't come with any hard mattes.

So I made some up that fit in the filter tray area and they're skinny enough that you can still fit a filter behind the matte.

They've been tested with the Misfit Atom but should work fine with any other 4x5.65 mattebox.
