Please note, I've made every effort to show the color of these keytops as accurately as possible; however, due to different monitor settings your display may not match accurately.  It may help you to know that the keytops are laid on an ordinary white sheet of copy paper that is about 92 brightness.

One octave of piano keytops, no fronts, includes one each A, B, C, D, E, F, and G. Simulated satin yellow, has grain pattern that resembles ivory (much better looking than plain plastic). Recommended glue is our Super Tacky Keytop Replacement Glue (a PVC-E substitute since that has been discontinued) - the best glue I've found for gluing porous material (wood) to non-porous material (plastic keytop) - available in multiple sizes in my eBay store (1/2 oz will be plenty for an octave, 2 oz for a set).

These are called "short heads" - the front, widest portion of the key (the "head") is 1-15/16" long from the notch where the sharp is to the front of the key, and is 7/8" wide.  The tail portion is 1/2" wide and 4" long for a total length of 6" overall. 0.070" thick.  The first A and last C have wider tails - 3/4" and 7/8" (same width as the head) respectively.

Also available as a full set of 52 in my eBay store, item #294848117468 or item #TBA which is a full set with glue included.
