Sand Castle Favors or Centerpieces (Made of Real Sand)

Here's a fairytale favor for a beach bride: sand castles with breathtaking detail, made of genuine fine white sand. How? A custom compound (could it be magic?) makes it hold its shape. Fabulous for favors, or put these to work as evocative centerpieces: place them in clear glass rose bowls (also known as "fish bowls") you've filled with water, on top of a small object (like a tuna can!) hidden with glass marbles. The castles will be beautifully magnified and add an outsized beauty to your tables. Sand castles measure about 3 inches high.
