A bloody big and sturdy cotton sack that hauls craploads of stuff. Your mommy will be very happy when you bring all your laundry to her in one of these. Or if you prefer more adventurous use, this can also probably carry the leprechaun’s whole gold hoard without breaking. Also pretty decent for some forms of historical reenactment. And the real Santa brings toys in a sack instead of shoving them in socks.
This is a very simple sack without any easy-to-break flippetyflaps. We were told that these are Czech, but they may as well be Czechoslovakian; the sack is such a timeless classic after all. Metal grommets at the mouth. A rope is looped through the grommets, and it functions both as a drawcord and a carrying strap. The material is thick, sturdy, and densely woven, most likely cotton. The color is sort of greenish brown, but it varies a bit from sack to sack.
Used Czech or Czechoslovakian military surplus. These are all serviceable and will last many years to come. But they may have some small stains and other signs of use. After all they are used.
