They are very well made and BRIGHTER than expected, thanks! The plastic used is not like the rubber of large road cones, but has a smoother, finer texture. thin and has no lumps like a highway bag. It's ok if your application allows it. I will use them to mark dowsing points and find metal for salvage and potential salvage points. These cones are ideal for a variety of terrain marking applications that require high visibility, portability, ease of use and high/low cost.
