The Aqua Pencil Tether is made from stretchable silicon rubber in a variety of colors. At each end is a novel self-locking feature that loops around itself to capture gear. Loop it through the hole on the Aqua Pencil and pull the other end through the hole in a Slate and your Aqua Pencil is secured. Or you can use the Tether to secure any other light-weight gear.
The Aqua Pencil Tether is 12" long and will stretch to twice its length without breaking or the loops pulling apart. Another tether will become available in the future for heavier task loading. Available in eight colors: red, yellow, orange, blue, green, black, pink and purple.
