I use them for ONE reason. The ones I use are white and reflective. It's helped me in a tracking situation. My first deer......I stuck an arrow out of my quiver at theplace I saw my buck first arrowed (he ran out of my set with the arrow in his side). I then placed another arrow at the tree where I shot him......and another on the line I saw him leave.

When Lisa and I returned to begin our tracking job.....it was almost dark. It was helpful to be able to look down the line he'd been on in the DARK and see the reflective ends of my arrows.

They're not JUST for aesthetics.
