Keep your water right where you need it! Magnetic cup attaches right to your stand.
I used to scorn the tupperware-with-extra-metal-clamp solution people had to attach their water cup to their stand. Too many pieces to lose, too big and bulky, too fussy. But I also used to constantly spill the water that was living in an open cup at my feet, or balanced precariously on my stand. This perfectly-sized watertight cup suits me perfectly – a strong magnet holds it securely to the stem of your music stand, as high or as low as you need it, no matter how fat or skinny the stand.
