These mugs are from the archives of Red Fern Glass, 1985-2025.  Use them for COLD DRINKS ONLY, hot liquids poured into these mugs will most likely crack the mug at the handle

Blown glass mug with optic pattern and strap handle.  The light cobalt mug is 120mm tall, 115mm wide including handle, and 73mm diameter at the top, signed "EP86".  That is  4 7/8" x 4 1/2" x 2 15/16".  All other mugs are a similar size but not exactly the same.  Be sure and include your color preference when you order otherwise the light cobalt is the default color.  Only one of each color available except for the dark amber which comes with either swirled optic pattern or vertical optic pattern.  Some mugs have the original signature from 1986-1988.  Others are unsigned but I can add a signature if requested.  I will just sign any unsigned mugs with my initials "EP" but not the year since the year could be anywhere from 1985-1990.
