These films I bought for a night cache Multi (Geocaching). Here has been important for me, the extremely good visibility while illuminating with a flashlight in tiny dots. Now the night cache is finished and I am absolutely thrilled with the reflective tape. At first I was concerned that the amount is insufficient to hire - now I have more than half are around here. Then was the fear that if it can be easily cut and glue on tacks: It holds very firmly - even on metal pins. Even on dirty metal signs I could stick easily and it keeps well. The reflector performance is really good, so I always a smile on his face did when I evening by bike abfahre the track where I glued the reflectors. I would recommend this film for Geocaching any further and buy yourself again.
