Corresponds perfectly to the expectations one might expect of reflective stickers. The trick sticks well (also watch out for the stick straight, otherwise you will damage the paint of your helmet) and reflects as much. After these are reflective stripes and not a mirror, so for you to see for yourself, take one photo with flash. The price is quite reasonable and sending very fast (2 days ago in Paris). And it is quite to the standards of Control. enjoy :)
