Small sandbags to use as a weighted anchor on the sides of any Port-A-Field field used on turf, hard floors (gym floors, concrete, etc.), or any surface where inserting anchors into the ground is not possible. Each small sandbag is 4.5" x 6" in size and comes with a 5" velcro strap to attach to the field lines. A velcro flap at the top of each bag allows one to easily fill or empty the bag with sand and securely close. Sand is not included.
