Guarantee and wear
There is no two-year warranty for this type of product; callus guards are considered a “perishable good.” Wear depends on many factors: the type of bars they’re used on, how they’re used, the user’s weight and their approach to the bar, which can affect impact and therefore wear, as well as training intensity and volume.
We recommend always checking the condition of the callus guards and replacing them if necessary—after 4–6 months, a year, or whenever you feel it’s needed—to always work safely on bars and rings and ensure optimal performance. For any issues, please contact us at customercare@stmnfitness.com
