Brand new Webkinz Long Sleeve Children's Tee with sealed & unused code tag to use online!   
This is not a heavy material, and it is one layer, even though it looks like it could be two shirts.  They are 100% cotton, but I found that they did not shrink when washed in the washer in cool water with a quick trip through the dryer. 
These are brand new shirts from Ganz, they come in plastic pouches, on which I have little size labels.  The last photo shows the shirt in a package.  Only a few have been opened in order for me to take pictures, or because I couldn't see the size without peeking.  The pouches are resealable though, so nothing is damaged. :) 
Super fun shirts for the kids to wear out or as sleep shirts :) 

The sizes are pretty generous and as roughly as follows: 

CHILDREN'S
S 5-6
M 7-8
L 10-12
XL 12-14
