GfN Pen Torch with Pupil Guage + Ruler
This GfN Torch has a metal case giving it a good quality, solid feel.
It features a Pupil Gauge on one side and a 7cm ruler on the other side.
Our specially designed clip allows you to use the torch in two ways:
1) Hold down the clip-end to turn on the light or
2) Pull back the top of the clip to keep the light on permanently.
The batteries and bulb are replaceable.
Please note that the image shows both sides of one torch.
