Shakespeare Earrings

The last time I browsed Cafe Press it was all about the clothing--t-shirts and hats and tote bags and such. Also mugs. I didn't realize they'd gotten into Etsy territory with hand-made jewelry items until I saw these earrings for sale. You can buy them here, but be warned, they come with a warning that the earrings are not for sale to, or use by, anyone under 12.  I'm not sure why that is. I can see they'd be a choking hazard for very young children but surely kids grow out of that phase by the time they start going to school?
