FIREFLY TRITIUM SUPER KIT MARKER (MINT) -
S$25
It's green color and the brightest one. Just bought to see
how it works. Text me at Eight4781164 if you are
interested.

Zip markers allow tent and bag zips to be seen, located and
operated in darkness, enabling immediate exit without using
electric torches or chemical light sources.
Simple, reliable and very effective, these markers enhance
operational efficiency and safety in dark and low light
conditions.
These zip pull markers remain continuously illuminated for more
than 10 years even during prolonged periods of complete
darkness.
No battery, switch, recharging or spare parts are
required.
Light is provided by a GTLS (Gaseous Tritium Light Source) that
provides a safe, reliable and self-powered source of
light.
Suitable for operation from -40'C to 70'C, they will continue to
work normally, even when used or immersed in water.
