2 Vintage Plastic Mugs Pale Green 1960s-1970s Mid Century made in avocado. These look like a slightly lighter color old Deka mugs in shape and especially in handle design. 

These cups are not marked, maybe an earlier (or later?) version of the Deka set. The only mark is “Made in the USA.” 

Mug diameter 3",

Height approx. 3.25"

Please see photos for condition and description and please note the wear lines on these mugs where they have been stacked together many times.
