This is a set of two Uniqlo Heattech shirts. They are a crew neck long sleeve and a high neck long sleeve, both in white. The size is 100. The crew neck has a lot of pilling overall. The high neck was worn less, so it has less wear and tear. Please purchase if you understand that these items are stored at home, are used clothing, and there may be oversights. Thank you for your understanding. Thank you for looking.
