The Datadart Atom Steel Tip Darts are designed for serious darts players looking for precision and accuracy. Made with 90% tungsten, these 21 gram darts feature 30mm barrels, perfect for excellent aerodynamics and smooth flights. The Atom bomb shape and high-quality materials make these darts a reliable choice for improving your game and achieving consistent scores. These darts have a few little marks on the barrels as they have been thrown just a handful of times to try out and I can say they are really fun to play with and you could actually use them as your full time dart surprisingly. The stems and flights are untouched and brand new. A real different type of dart for me but really enjoyed them to be honest and I'm sure you would to.
