These pucks have been personally hand-signed by William Karlsson and Jonathan Marchessault. They are officially licensed by the National Hockey League and come with an individually numbered, tamper-evident hologram from Fanatics Authentic. To ensure authenticity, the hologram can be reviewed online. This process helps to ensure that the product purchased is authentic and eliminates any possibility of duplication or fraud. The pucks will come in a mahogany framed shadowbox that measures 15.5" x 25.25". The shadowbox will feature an image of the players, the team logo as well as their statistics.
