I received this as a Secret Santa gift from my previous job at the end of 2021. I did open it, but I never ended up using it or tearing any pages off. Its 100% intact, all pages are still there, and the calendar itself is pristine. You're essentially buying it for all the neat Pokémon factoids on all the pages rather than marking dates, which is still fine for any Pokémon collectors. Buy with confidence!
