Our Stellar Bird blocks are handmade out of colorful laminated pieces of western red cedar with a hardwood cherry base to improve the voice quality. They have a 7/16 inch groove which will work with Stellar flutes in the keys of A, G, F# , F , E and D. It is still a good idea to measure the width of your fipple holes before ordering to make sure it will fit.
If you are replacing a lost or broken block or need a block with a different size groove please contact us for more guidance. 

Note that this block may not fit a flute made by another flute maker so it is best to check with the person who made your flute if you are able, or send us an email for more personalized help.

These kit blocks have a 7/16 groove that is suitable for all three keys of our pre tuned kit as well as our Basic flutes and our Premiere flutes in the keys of A, G, F#, F, E ,and D. Choose between our various animal shaped blocks or our unshaped block.
