Dart weight is guaranteed by Unicorn. A rarity with any set of darts. Ringed barrel is easy to grip and feels good in the hand. Replacement of the point requires a visit to your local dart shop. Fixed point darts can bounce out.
Unicorn darts are hard to find.
There is no doubt in my mind that these are high quality darts. My hunt in locating these was a tough one. John Howie, the proprietor, was easy to deal with. The entire transaction was done via email. Jim, from Dart Pros in Modesto CA, also has these darts available.
