Bought a Hitachi Magic wand and I gave it to my wife several months after on her birthday managed to keep the wand hidden that long. She LOVED it however it was missing something. And well this wand head was it. The blue sleeve goes OVER the head of the magic wand and fits snugly and does not move during use. The hitachi wonder wand attachment (although it is well over four inches long) is hollow as not to add too much weight to the wand. It cleans up well and washes clean with standard soap and warm water. In all a perfect purchase if you already own a magic wand. And if you do own one and you are missing the hitachi wonder wand attachment it is well worth the purchase.
