I love the lego bracelets. I wonder if my boy kiddo would dig one? We have a lego watch that's pretty cool, and I totally love the removable spider. Hm...boys are tricky, too.
I think a boy could rock the grey one. There are lots of cool boy things you can add...lego rats, actual lego pieces, etc.
If there is any interest I could make some like these that would be 2 for 1 point.
