One of my clients, planning ahead for breastfeeding with flat nipples, had this sent from Mexico:

http://www.anumex.com/anuncios/pezonera-de-plastico-le-roy-872917.htm

It's a hard plastic base with a rubber top that easily comes off from the base. It's about 2+ inches deep. 

We didn't use it, but it's new to me, so thought I would share.
