FLATS

Denver Rock Boxes' flats are shipped unassembled (“flat”). When assembled, the
inside of the bottom and the outside of the top are smooth and white. Flats can be
assembled using tape or glue, but stapling is recommended for the best appearance
and to maximize the strength and durability of the flats. One box of staples will
assemble hundreds of MFS flats.

​

Our Flats are made with 200 Pound weight card board, to support large amounts of specimens. That is why our Flats are a bit more expensive then our competitors.
