Cupcake Holders for Terraria?

Cupcake holder from http://www.weddingwarehouse.us/

Thanks to my friend Gennie for sending along the link to these cute "cupcake holders."  These would make cute mini-bell-jar terrariums and are priced at $16.98/4-count and a deeper discount for larger purchases.  See http://www.weddingwarehouse.us/ for more info.
