Classic of the 90's that, believe it or not, is still in production.  The Keeper had a huge success in the 90's because it was fashionable, but today it's still around because it's really efficient.  Seems like that should be a joke.  Seriously though it seems like it could be really useful.  I was never that organized to actually get the full potential out of the Trapper, but today I actually may look into getting one.  The 90's version is much cooler than the one today as it came in such an array of amazing neon colors and epic graphics, today's Trapper Keeper is less epic but still has the same functionality.  If you have trouble tracking it down at a store it's on sale on Amazon for $11.36.  Check out some vintage footage of the ridiculously sweet 90's Trapper and the more current version.
