Like the classic percussion instrument, this toy Triangle has three sides and curved corners, where one corner has been designed deliberately not to join. This allows the instrument to vibrate and create an audible noise and also a palpable sensation for your little one to feel. This is great sensory toy that encourages your child’s musicality and sense of rhythm, as well as further their hand-eye coordination. Add this Triangle to your growing collection of beautiful toy musical instruments.
