The size is 7 (55.8cm). I purchased it from the online store. The seal is still unbroken. This is the first triple collaboration between fashion curator Motofumi "POGGY" Kogi and New Era, partnering with the Yomiuri Giants. Two silhouettes were selected: the [Pillbox], characterized by its medicine box-like form, which POGGY particularly favors, and the [Retro Crown 59FIFTY®], which offers a soft, low crown for a classic fit. Among them, the [Pillbox] is a silhouette that symbolizes the Pittsburgh Pirates, which has a strong connection to the "Old School Hip Hop" culture that POGGY respects, and it has been adopted for the first time by a Japanese team. The silhouette is the [Pillbox], which features a flat top and a medicine box-like form. It does not have size adjustment and is available in sizes with approximately 1cm increments. Anyone from those with smaller heads to those with larger heads can wear it in their exact size.
