Sold by the dozen, these are miniature prairies in bottles! Each one contains natural prairie grasses and flowers, Oklahoma's iconic red sand, and a beautiful, tiny barite rose rock. The bottles measure 1" tall (not including cork) and about 1/2" wide. The corks aren't glued so they can be opened, if desired. These are easy to turn into pendants, are fun and educational for parties or show-and-tell, make great ice breakers at group events, and are perfect for weddings!
