Oeko-tex certified 100% cotton t-shirt by Hanna Andersson. This garment is in excellent condition with no stains, tears, pulls, or unusual stretching. We wash our clothes in Molly's Suds nontoxic detergent, so this remains free from harmful chemicals. Note: there is some marker that says "Leo H" on the tag put there by someone at our son's school. Other than that the shirt is flawless. Combine with other items in our closet into a bundle for a great deal on lots of nontoxic kids stuff as well as some adult and household goods.
