Gecko, I like the worm texture and the overall look.
I have a couple comments.
I agree that the finish should not be glossy because when wet the box could slip from your hand.
Shellac, unless covered with a lot of varnish or polyurethane will spot if wet. Shellac hates water.
The clasp, (IMHO), is much better than magnets. It will hold the box closed if it gets hit or dropped.
How come every time I hit "Enter" the page scrolls down to the text below the reply box?
