Review on Stay Safe on the Road with Lenmumu Safety Triangle Kit: Foldable 3 Pack of Roadside Reflective Early Warning Signs by Adrian Allen

Not very heavy but good for the purpose. If I were to drive a tow truck or crash crew I would DEFINITELY get better, but I don't, so they'll do for my purposes. Designed more or less for one-time emergency use only, they're certainly compact and easy to store. The inner fabric doesn't feel very durable and the sleeves are so tight that it's quite difficult to put the triangles back in.
