They meet all IIHF standards and the rigorous specifications of the Canadian-American National Ice-Hockey League, including attributes like hardness, weight, thickness, rebound elasticity, flatness, and diameter. While we strive to provide the best durability for our pucks, please be aware that using custom pucks during games can lead to logo wear. The rough ice surface, powerful slapshots, skate blades, and various other factors create a challenging environment for the logo. The type of play also influences how long the logo remains intact. For instance, in an NHL game, a logo might only last 4-6 minutes on a puck before it wears off. On the other hand, a custom puck can often endure an entire season of Squirt-level play with minimal damage. Due to the diverse conditions and environments that pucks may encounter, we cannot guarantee the lifespan of a custom puck in gameplay before the logo shows signs of wear.
