Heavy-duty non-rusting, jumbo size plastic box measuring 3 7/8" x 1 7/8". The dual m agnetic system is made to hold. Inside dimensions are 3 1/4" x 1 7/16". Very well known for making great geocaching containers in awkward places!

Note: Our 2" x 4" Official Geocache stickers will fit on these nicely with a little trimming.
