Munsingwear magnetic putter cover. The mascot penguin also functions as a putter cover catcher, which I think is convenient. I bought it new and it's a beautiful item, only attached to a putter once at home. For blade-type putters. It's mostly unused, but I'd like to sell it to someone who understands that it's a used item, so please consider it. *Also listed on other sites. Please forgive me if it sells out.
