Mizuno navy and white baseball wear, size L, with player signature. - Brand: Mizuno - Size: L - Color: Navy x White - Signature: Player signature #19 Thank you for viewing. This is a uniform I received about 10 years ago as a prize from 7-Eleven. It has the signature of Masanori Ishikawa, a player for the Tokyo Yakult Swallows. It has never been worn, but it has been stored by a private individual.
