Lucky & Me | Ryan Boys Woven Boxers | 100% Cotton Children's Underwear (5-Pack)

Do these come in 3T?

Are these three panel traditional boxers, or are they more like shorts? There isn't a picture of the back. Thanks!

do these have a button fly?

Dear seller, please start making these in sizes all the way up to big boys xl? it's so hard to find 100% cotton any more!
