Berty tubes, named after a fine geocacher from the Houston, Texas area, are heavy duty plastic tubes with a white body and a color cap.
Each tube is ~50mL, or 2 Fl. Oz in volume, stands 4" tall and is 1 5/8" wide at the widest point. The tube body is 1 3/8" in diameter.
The texture of the tube is perfect for applying your favorite camo, being tape or paint or even just as is.
Cap color is mostly black, but is subject to change as these came without caps and we've had to scrounge around to get what we can that fits. Mostly Gatorade and Powerade caps.
A ready-to-hide log sheet is included.
