3M Speedglas Visière de meulage transparente à large vue pour casques de soudage de la série 9100

i have been using 3m welding shields for about 30 years and have been using the 3m 9100fx shield with flip up grinding visor for over 10 years now and it has served me well. the biggest complaint i have for the grinder lenses is that they are wayyyyy over priced. I give the shield 5 stars bit the expensive grinder lenses 2 stars because of the unreasonable price 25.00 for one? insane
