PLEASE READ ENTIRE DESCRIPTION! These are "AS NEW" unused paints leftover after my brother passed. He was the painter in the family - if you have any technical questions you will have to refer to the manufacturer's website. They were stored in a climate-controlled area. The temperature range was always within 60-80⁰ F. They were stored with the caps down. I performed the squeeze and sniff test on them, they are fine. No returns - This is a one-time deal. I am mildly allergic to paint; I don't ever want to see these again. UPDATE: A customer has taken exception to me using the description "UNUSED" because the tube that he received was "dented". As described in the listing I DID A SQUEEZE TEST on all the tubes to ensure that they hadn't dried-out. The photograph shows ALL the tubes for sale. If you purchase a tube, it WILL BE IN THE PHOTOGRAPH! Review the photograph to ensure that you will be happy. The tubes are in numerical sequence in the photo. U.S. SALES ONLY!
