These 7-7/8” diameter metal dials feature quality printing with epoxy based inks, on a polished flat aluminum disc. approx. 1/16" thick. Black Arabic numbers are printed over an Ivory background. I would suggest using black hands in the 3-1/4” to 3-5/8” range. It’s also available in 4-1/2” and 6” sizes with Arabic (regular) numbers or Roman Numerals. Please remember to remove the protective plastic film before use.
