Reviews
"Golden Yellow" is not an accurate description
"I was disappointed to discover that the "Golden Yellow" color is more of a "Sad Mustard. " Still works great, though."
Great classic cap
"This classic cap is true to it's name - classic. The small size is great and compact, not too bulky or not too small. There could be more colors."
