These are well used, but have lots of life left.
My littles ones tossed these out of the stroller many a time and they keep in keeping on.

Comes with the sippy cap style top, great for early
users, but can work with other styles of Klean Kanteen tops.

12oz - only selling because my children are older now and need more than 12 oz on the go.

Well used Condition
$10 for all 3 or $5 each if I break them up.
