It is very nice because it does not interfere with the next helmet even in the helmet storage area. However, it was only one if I thought that it was two pieces. I think that these detailed product descriptions are missing here, it seems like the same thought many times.
Although I bought two, since about 6 pieces are needed to attach the light to the helmet, I had to purchase 4 more. I tried purchasing a Toyo Safety goggle clip about 1/4 in price, but since it is functionally almost the same, when purchasing for the same purpose from now on, I will purchase Toyo Safety's goggle clip.
I think that goggles are very easy to use items because they can be immobilized and the clips never loosen. Although this kind of thing is broken or it is easy to come off, this item is a product that is hardest to break and has the most sense of hold.
