The Van Buren sounds are about 10.5 inches long and are Jshaped with a single curve near the tip. The flat handle side is made for holding and is easier to maneuver. There are eight sounds in the set with sizes ranging from 8FR, 2cm in diameter to 22FR, 7cm in diameter. Many recommend this as a starter sounds kit becuase the J shape prevents sound from getting lost and the width of these sounds are reasonable. Small, Run from 8 to 22 french. Large, Run from 18 to 32 french.
