Adidas Women's Tennis T-shirt, Long Sleeve Material: 100% Polyester I haven't worn this very often, but it has been used, so please refrain from purchasing if you are concerned. Also, it has been stored at home, so there may be some folding wrinkles. Shipping will be without packaging, or in simple packaging using recycled materials, and will be the cheapest method such as regular mail or Mercari delivery. Please understand this before purchasing.
