This is a box with lid to store garden seed packets.  There are no supports or brim needed.  I intentionally printed it out of black so light would not penetrate.  Other colors could be printed, of course, to the individual's preference.  I have this storing my seeds for my hydroponic systems and  works well.  I put some small paperclips in there so when I tear the seed packet corner I can fold it over and use the paperclip to keep the packet closed.
