These Skilltoyz kashaka (also known as aslatua, Asalato or Cas Cas) are robustly made Rhythmic Percussion Instruments. The strong and hard plastic shells are filled with iron sand for a nice loud shaker sound and the shells have a good percussive sound when they hit. The two shells are linked with a strong thick adjustable length cord, making these adaptable to your hand size and very comfortable to play. Cord length suits adults and children. Our Skilltoyz kashaka are sold individually. Most customers buy a pair of these for two-handed play, so if buying more than one you can mix and match your favourite colours. Price is for one set (ie. two shells and one cord). You need to buy two sets for dual-handed play.
