Fortunately BrickWarriors did!
BrickWarriors.com, (as can the Warrior Packs), and right now the Warrior Packs are also showing up at Five Below stores, if you are lucky enough to live near one of those.
Also available on BrickWarriors.com are many other custom pieces for all sorts of minifigure fun...with one theme in particular that really got my goat going:
The blade on top is a brilliant design touch. This thing would have been plenty cool as a simple jack in the box, but making it deadly really adds to it's awesomeness and makes this thing the perfect Harley Quinn accessory.
Finally, Harley has a...juggling pin? What's so exciting about a juggling pin?
The juggling pin hides a removable knife! Another genius design!
I love this stuff! The concept of bagged minifigure accessories is an idea that should have come to fruition years ago. I know a few folks have been making and selling Lego minifigure accessories online for a while now, but the fact that BrickWarriors has been able to get their Warrior Packs into a retail establishment is just wonderful and a great sign for the future of this hobby.
Be sure to check out BrickWarriors.com to see all the cool custom accessories, and if you can find a Five Below store, look for Warrior Packs there too!
