Buying for an office with several ST machines? ST-2000, ST-3000 and ST-4000 share this exact ink — the set on this page is the fleet refill. And a standing reminder for EcoTank buyers generally: 502 and 522 are different, non-interchangeable families; no ST model takes 522.
Singles and the 4-bottle set both carry our lifetime warranty and 1-year free returns.
