Although tough the MegaGlow Safety Marker is NOT indestructible the inner Tritium Isotope/Betalight can break and if this happens it will stop glowing. So please understand that if you break the Isotope inside the MegaGlow Safety Marker we will NOT give you a refund or a replacement. The tritium Isotope/Betalight inside can be broken if the MegaGlow Safety Marker is dropped onto a hard surface or if the MegaGlow Safety Marker receives a hard blow. The outer polycarbonate case of the MegaGlow Safety Marker is tough and may not show signs of damage even though the MegaGlow Safety Marker has received a blow hard enough to cause damage. Sometimes to the Human Eye no damaged is visible and light will stop emitting, this is not a faulty MegaGlow Safety Marker as it is Scientifically impossible for the Isotope/Betalight inside to stop working unless breached or past the time scale of its life.


In order to prevent damage in the post the MegaGlow Safety Marker is placed into a padded jiffy bag.

Brightness appears different in certain colours, this is not down to lower power in certain colours but purely down to the nature of the colour. An Ice Green or an Ice Blue we see as a crisp colour whereas an Ice Purple or an Ice Red we see as a duller colour. The MegaGlow Safety Markers supplied by us here at Iceatope are classed as full maximum power output for colour.

Please remember that colours may look different from screen colour due to the type of photography used.
Below is what we believe to be order of brightness.
