Review on B REFLECTIVE Éco BASIC - 10 Retro Reflective Stickers Kit for High Visibility Safety at Night - Universal Adhesive for Bike/Stroller/Buggy/Helmet/Motorbike/Scooter/Toys - 2 Pack, Black (7 x 1.8 cm) by Glenn Cho

The black variant does not appear on the black parts of my bike, which I prefer as it doesn't detract from the look of the bike. I put decals on the seat post, cranks and stem, they are all metal and stick well. I also put a few on my SKS Bluemels fenders which are plastic composite and they are already starting to peel off. In the future I will probably only wear them on metal parts. I think it's a good investment to increase your safety when driving in low light conditions. shapes if you need.
