Sealed. Opening and using/unsealing contents and returning will result in a partial refund up to the amount I'm able to get selling it open. THEY have a 2023 E X P DATE, They will still work fine. I've sold many from this era. I'm not going to deal with returns for this. theres lots of information about cartridges from this era still working fine and I will reference that along with the other many Ive sold with similar dates.
