Failing a real hardwood blowpipe, you can buy the handsome quiver of stout rattan-bound bamboo with the poison darts (minus the poison), both authentic, and a shorter pipe of bamboo that does a perfectly serviceable job of blowing darts into your cork dartboard at home.
Dart blowers can be made with hardwood or bamboo.
All darts come with complementary flasks of poison to dip them in.
