All items were purchased a few years ago and stored indoors after use. 1) Underglaze The bottle size is 30ml. The remaining amount is about half for EZ033 and EZ058, and about 60-70% for the others. EZ012 Jet Black EZ026 Yellow Orange EZ033 Ivy Green EZ037 Black EZ058 Poppy Orange EZ075 Passion Red 2) Underglaze Pencils The tips are a bit hard, but I think they can be used if sharpened. 3) Gold Paint Marker The remaining amount is unknown. I confirmed that the liquid comes out of the pen tip. Replacement pen tips are also included.
