Condensation control lace seal. I received this, but I already use a similar product. I'm offering it to someone who needs it. Please clean the area where you want to apply it before use. Size: Approximately 35 x 200 cm How about applying it to windows to absorb and release condensation? Materials: Polyester, Nylon, Acrylic Thank you. I will fold it and ship it via non-standard mail.
