The Square Jellyfish Jelly Legs Micro Tripod is incredibly light and only weigh less than 1/2 an ounce. Jelly Legs are very strong and made of a high grade Polycarbonate / ABS plastic. When folded Jelly Legs are just 2.75″ long. When open they span about 4″. For some additional flexibility there is a thumb screw that can increase the resistance and help the legs accommodate uneven surfaces. Jelly Legs were designed to hold pocket cameras and smart phones with a tripod mount. For added flexibility add the Micro Ball Head or larger ball head for heavier loads.
