does this product has other key? such as F G D. Thanks.

It is, from left to right, top row: G C E G C E G C E G C E. On bottom row it is, left to right: D C F E A G B C D E F G A C B E D G F C A E B. This is an incredible harmonica. The numbering system is strange to an American as it goes 5 2 1 4 3 6 5 7 1 2 3 4 5 6 1 7 3 2 5 4 1 6 3 7 but is an easy concept to pick up. I strongly recommend this over a Hohner.

How does the numbering order on this harmonica translate to others? There is no # 1 through whatever. It goes like this: 5 2 1 4 3 6 5 7 1 2 3 4 5 etc

The reason is complenary notes in that key to the selected note. You will notice this also works when you pull air in through that note.

It shows 2 color choices, hf and 24. Yet we don't see any color difference. Can someone explain the difference between the hf and 24?

I went to the page for the harmonica and there are three pictures, one color. You may be confused by the lighting??

What is the difference between a child's size and adult size ?

the childs size is smaller???? This harmonica has a very large range longer than what most would expect.
