I just clicked on your link in your note that said "Musical Instruments". I went back to it and copied and pasted it below:
Musical Instruments
The 8-Note Board Thumb Piano (Kalimba)
This is our simplest kalimba. It is sturdy, easy to hold, and has excellent sound. With 8 keys, it is available in mahogany, walnut, or cherry.

I hope that helps! It looks like it already has a finish on it and I would prefer unfinished wood and for it to be smaller although I sort of like the oval shape. The one I sent the photo of to you measures 5 1/4 x 6 1/4 inches. The edges and corners are rounded but the shape is square. If I had the hardware, perhaps I could figure out how to make them except that I am not adept at using a table saw or sanders. I use a drimmel tool to work with Ostrich Eggs but mainly do pencil drawings. I just love the thumb pianos and would love to paint some for Christmas gifts this year. They are so unique. I sure appreciate all your help. Thanks so much! jrebel7
