Beautiful boxes! You are very talented.
You would help us greatly by providing some additional details. Size and dimensions of each piece is a good start.
What species of shells do you work with? Are these based upon traditional designs? If so, please elaborate on your cultural background (ie) folklore and culture.
Perhaps a small description on how you choose subject matter, harvest shells and the time it takes to make each piece.
Again, these are remarkable pieces and I thank you for sharing them with us.
