Discounted, used Prototypes + Flops

I am very serious that every new product is first used and evaluated in the capacity I am expecting my target audience will. As a result of this however, a fairly large stockpile can build up from the very first casts.

These items have been used intimately prior. As such, they have been sterilized through heat, soap, and isopropyl alcohol in the relevant locations before being put up for sale.

They can be considered significantly discounted flops, partly because they are pre-owned, and partly because they are the first instances of a product in different firmnesses, textures, orifice sizes, etc. 

They are sold with flaws and all, discounted to a degree I would not find objectionable for a second hand toy.
