I like the bamboo comb

The combs are also very sharp and have hard edges which can actually be very rough on your tongue and inside of the mouth if played too long.

The Comb they say it is Glue Laminated Bamboo, it is slick, slicker than pear wood or the plastics(PVC) on the others

The combs and covers are very smooth.

The combs are smooth, the covers are smooth, the size of the harp is a perfect fit for the hand.
