Please note, these items are handmade and so each COBRA turns out slightly differently, including differences in color of the wire. The pictures are for purposes of illustration only.

The COBRA is an accessory for the flute. It is worn on the forefinger and supports the flute, making it easier to hold while playing. The COBRA is handmade from metal with flexible plastic pads, so it will not scratch the flute nor does it hurt the hand.

The COBRA is constructed to be flexible enough to adjust by hand, yet strong enough to hold its shape after adjustment. The COBRA should be adjusted to fit the size of the left forefinger (index finger), within the range of US ring sizes indicated.

COBRA B is designed to make playing the flute more comfortable even over long playing sessions. It has a double ring for extra support, and an extended, jointed "tail" to keep the flute more stable.

The rings come in several colors; the "heads" and "tails" are all black.
Choose from six ring colors: Black, Silver, Gold, Pink, Blue, Turquoise.

Choose from 5 sizes to fit the left forefinger:

X-Small (US ring size 5-7), Small (US ring size 7-9), Medium (US ring size 9-11), Large (US ring size 11-13), and X-Large (US ring size greater than 13).

The Cobra is worn on your left forefinger (index finger) close to the line where your finger meets the palm of your hand, not closer to the knuckle where a ring is usually worn.The X-Small Cobra fits fingers measuring less than 2.14 inches (54.5 mm); the Small Cobra fits fingers measuring 2.14-2.34 inches (55-59.5 mm); the Medium Cobra fits fingers measuring 2.35-2.54 inches (60-64.5 mm); the Large Cobra fits fingers measuring 2.55-2.74 inches (65-69.5 mm); the X-Large Cobra fits fingers measuring 2.75 inches (70mm) and larger.

For more details on how to choose the size please see the FAQ on our website:

If you choose "Custom" size and put a note with the exact size of your finger in millimeters in the "optional note to Misticmedia" box when you checkout, we will make a custom sized Cobra ring for you, at no extra charge.

Safely arrived. I bought two “Cobra B” for Mum and myself. We took our forefingers size and i wrote them when i ordered. I asked him to make smaller than actual our size. Because i had ordered “Cobra C” before and i had him to make the right size. But it was too loose and too big. Before we used cobra B, we had to adjust it to our forefingers a little by our hands and longnose pliers. But it wasn’t much difficult or it didn’t take lots of time. They support us when we play the flute. Mom doesn’t feel pain with it on her finger but i feel pain a little because of fibromyalgia. But they are working well.

I bought it for my Baroque flute and it fits and works wonderfully! I have very short thumbs and wasn't able to balance the flute well, which caused issues with technique. Now I can balance and stabilize the flute much better!

Safely arrived. When i ordered, i wrote my forefinger size, but “Cobra C” was too loose and too big a little for me. So i had to fix “Cobra C” by myself. It’s quite difficult for me to adjust it to my smaller size by long-nose pliers. I think it needs a trick for wire works and pliers works. I have a little bit of trick because i make accessaries by myself. But it took much time to do it. After i did, cobra C supports me playing the flute. It’s easier to play high notes than before. I don’t have much pain while i hold the flute for a long time. I think cobra RTC works well. If you use it, you should grip its edge. So it’s often problem for me because my hands often are shaking.
