Good set of small insulators for routing car radio and amplifier power cables through firewalls and other partitions. worked very well and the storage box was very useful. Quick update, weeks after purchase I rewired a 1985 Porsche Targa and had no eyelets for the headlight harness. I was surprised that some of them fit perfectly. Too bad the kit only included 2 of the 4 I needed for all the work.
