Shiny, stretchy tape is smooth (but not slippery!) and easy to apply.
$10 for one set ($5 extra for shipping if you can't pick it up, regardless of the number of rolls ordered) - enough for a set of vintage road bike drop handlebars - 2 rolls and 2 end caps.
I have a few sets available, in several colors:
red/white/blue (USA / Netherlands)
red/white/red (Canada / Austria)
