As perfect for bikes

I bought these bands for the helmet and the bike of my son.
They adhere well to one (plastic) as the other (iron).
They are discrete (very important for a teenager) on their size and color.
And they reflect the light; Black then dyed a silvery gray.
Do not replace the bike lights but provide a good supplement, it is never too visible on the road!

Delivery with one day ahead of schedule, thank you fast and efficient seller.
