Our rubber stamp with permanent and waterproof ink is PDGA compliant per 813.01-B-3 (Marking with dye or permanent marker ink). Our stamps are shipped with an ink pad and archival (permanent) ink. These will last as long as your disc does and can stamp as many discs as you please.

Our Stickers are not PDGA compliant per 813.01-C-3 (Adding a material of a detectable thickness such as paint). Our Stickers are made with waterproof vinyl stickers. These will not change the flight characteristic and the weight is negligible. These are a great (lower cost) solution for those that dont play PDGA sanctioned events or that are willing to remove as necessary.  Stickers will last for years, including being submersed in water.
