The Brittany needles are made in California from sustainably harvested birch wood. The wood has a smooth but not slippery finish so the Brittany needles are good for knitters who typically have a loose tension because they provide some "grip". The wood also is warm to the touch so these needles can be more comfortable than metal needles for those with sensitive hands. The somewhat blunt tips make them a good choice when you are working with yarn that is prone to splitting.
The needles have a 5 year guarantee against flaws and breakage from normal use.
