HaPa's Dafs are made in a variety of fixed (Pre-tuned) and tunable forms. These Dafs are made with Remo's synthetic drumheads known as "Fish Skin", that has a very high resistance as well as a pleasant and warm sonority. The feel and looks of the “Fish Skin” is almost identical to a natural skin. There's no sign of common talc or synthetics.

Specifications of pre-tunned Daf:
It should be noted that in circular instruments the wider the drum shells are the higher the bass sound is. The reverse is also done. Therefore the pre-tuned dafs are made with four different widths of drum shells, in order to provide different sound tastes and more options of choice for drummers and users with different sized-hands.
Another specification of these drum shells is that they are made by wood carving instead of bending process. Pre-tuned dafs are made of 36 and tunable dafs with 60 wooden pieces, which leads to a greater resistance of circular shape of the drum shell. As a result, under pressure, heat or cold, the circular shape of the drum shell won’t change over time.
