Photo 1, Marker pen was excellent on two occasions of use. Easy to use and crisp letters on label and I was very pleased with result.However, the Pen was then stored in a cool location and the top was secure on nib when not in use.After two uses, despite vigorous shaking and pumping, ink struggled to reach nib or there was too much ink on the nibNib then went out of shape and dried quickly resulting in Photo 2, where letters were tricky to produce compared to photo 1.Disappointed as this marker pen was not cheap!

I used the pen to mark our house number and road name on our plastic refuse collection bins and polypropylene recycling bags. They have stood up to recent wet weather and rough handling by the bin men without any fading or cracking. Long-term durability remains to be seen, but it is easy to write over again. The pen needs to be primed by pressing on a hard object a few times until the ink starts to flow and it needs to be stored indoors in a warm temperature - if the pen gets too cold the ink will not flow.
