wow, the was a great bargain for the price.  i just bought to fill in an extra amount i was needing to spend to get free shipping if i remember right.  
when these arrived, i decided that was a great bang for the buck and i would be ordering more for gifts.  they are bright shiny and light weight which i consider a plus.  sizes are fantastic.  will suffice any need.

Pros: inter stack.  easy to clean and store.
Cons: no cons here
