Gagalay 63XL Black Ink Cartridge 2-Pack, Remanufactured, B7RT5AN

If your HP printer uses a 63-series black cartridge, this Gagalay 63XL two-pack is designed for compatible DeskJet, OfficeJet, and Envy models. The listed cartridge identifier is B7RT5AN.

Both cartridges are black and remanufactured. The listing gives an approximate yield of 750 pages per cartridge, or about 1,500 pages for the pack at 5% page coverage.

Would a two-pack suit your printing routine better than replacing cartridges one at a time? The answer depends on your printer model and how often you print, compatibility comes first.

Key points

This pack includes two remanufactured 63XL black cartridges. The stated page yield is an estimate based on 5% coverage, so pages with heavier black coverage may use ink differently. Treat the figure as a reference for comparing supplies, not a guaranteed page count for every document.

Compatibility is listed across several printer families. Examples include DeskJet 3634 and 3639, OfficeJet 3830, 3833, and 5255, and Envy 4510 and 4520. The full list also includes other models in those families, so match the exact number on your printer against the product’s compatibility details before ordering. The description identifies these as remanufactured cartridges and mentions upgraded chips, it does not establish compatibility with every printer that uses HP ink.

How to use it

Install a cartridge only after confirming that your printer is one of the supported models and uses HP 63/63XL black ink. Follow the printer’s normal cartridge replacement steps, then use the printer’s prompts to complete setup. The listing does not provide separate installation instructions, so the printer’s own guidance is the appropriate reference.

A two-pack can be useful if you want a second cartridge available when the first runs out. If you print infrequently, consider whether you need two cartridges at once, if you print regularly, having a spare may better fit your routine. It suits you if your printer appears on the compatibility list and you are comfortable choosing a remanufactured supply rather than a new cartridge.

Best use cases

This pack is aimed at routine black-ink printing on supported DeskJet, OfficeJet, and Envy printers. It may fit household or home-office use where documents are printed regularly and keeping a spare cartridge is convenient. The listed yield can help set expectations for text-heavy printing, but the 5% coverage condition matters: graphics and pages with dense black areas can consume ink differently.

Compared with buying a single cartridge, this pack gives you two replacements in one purchase. A new, non-remanufactured cartridge is a different buying approach if that is your preference, this listing specifically identifies the cartridges as remanufactured. Not the best choice if your printer model is not included in the stated compatibility information.

Before you decide

Which printers are listed as compatible? The compatibility details include selected HP DeskJet, OfficeJet, and Envy models, including DeskJet 3634, OfficeJet 5255, and Envy 4520. Check your exact model number rather than relying on the series name alone.

How many cartridges are in the pack? It contains two black 63XL cartridges. The stated approximate yield is 750 pages per cartridge at 5% coverage.

Are these new cartridges? No. The product details describe them as remanufactured and mention upgraded chips. The listing also states a 24-month warranty, check the seller’s terms for the conditions that apply.

When it makes sense

Choose this Gagalay pack when you have a listed compatible printer, need black ink, and prefer having two remanufactured cartridges on hand. The main decision points are the exact printer model and whether remanufactured ink fits your preference. If either is uncertain, verify the model against the full compatibility list before choosing this pack.
