Class up your bike tool bucket with these shockingly chrome-plated allens, 10, 8, 6, 5, 4, 3, 2.5, 2, 1.5mm with a ball head on one end.  The chrome isn’t important and probably isn’t environmentally friendly, but that’s how they come, that’s what we’ve got for you, and once you’re over the “I don’t need the chrome” part of it, you’ll grow to appreciate the high visibility of them.  So far the chrome seems durable.
