A putter head cover with colorful embroidery. The colorful snowflake embroidery on the black synthetic leather is very beautiful. It opens and closes with a flap and has a magnet. The outer dimensions are 13cm wide and 11cm deep, and the inner dimensions are about 1cm less in each direction. It is large enough to fit the head of a Yonex Triprinciple putter, so I think it can be used for many mallet putters. I put a putter in it to try it out after purchasing it, but I have never used it on the course.
