Molded in silicone rubber for durability.   Just over 1" tall, they are suitable for use with 1/32 or 1/24 scale layouts.   Make your track environmentally responsible and politically correct with this colorful scenic item. Cut lengths of small-diameter plastic rod and paint them as beer cans to fill up these tiny trash receptacles.  Stuff a 1/32 scale figure head-down into one to remind you of what you'd like to do to your boss or your least-favorite politician. Rub off the recycling logos and use then as scale  tree planters, too, further reducing your miniature raceway's carbon footprint.  These are only a few of the many creative uses you'll find for these must-have layout accessories.
