Here we have a 7cm B Love Gong Flummie mallet.     I purchased a set and sold off a couple i did not need.   I used this one day for about  a minute. .  one small lightly smudged spot.   This is very good mallet in very good condition,   These are pricy and hard to find.   It is very nice.    These are unique friction  / Flummie mallets.     Research how to use these.   They are different.   Than any other brand.
