Keypeg is remarkably low profile, elegant, and easy to use. One Keypeg set includes two pegs and two keys. Keypeg is installed by a luthier with peg shaving tools and expertise. No alteration is made to the cello or scroll itself. Using Keypeg simply means keeping a key in your case and probably one more on your key ring.
The key has a larger surface area and creates more torque when placed in the palm of the hand, so you'll find that it's a bit easier to turn pegs.
Keypeg is available in the set of two pegs and two keys.
If you have an existing relationship with a local luthier, you might call and see if they already stock Keypeg. You will need a professional luthier to install it, and they will appreciate the call!
