This set earns the top spot because it offers the perfect balance for occasional office use. You avoid the clutter of a massive inventory while ensuring you have a fresh replacement ready when a ribbon fades mid-calculation.
I prefer this option because it minimizes the risk of ink drying out in storage before you can use it. It is a fiscally responsible choice for any home office or small workspace. Just be aware that generic rollers can sometimes show slight variations in darkness compared to the original Canon parts.

2. IR40T Calculator Ink Roller IR-40T Black and Red Calculator Ribbon, 12 Pack
This bulk package is ideal for high-volume environments where the calculator never stops clicking. If you manage a busy retail shop or a high-traffic accounting desk, this is your most cost-effective solution.
I find that purchasing in large quantities removes the panic of running out during tax season. However, ensure you have a cool, dark place to store these to prevent the ink from losing its potency over time. It is a rugged choice for heavy printing demands.
Frequent users note that the bulk pricing lowers the cost per unit significantly.
The two-color ink mechanism is reported to work reliably for most users.
Some buyers mention that the ribbon longevity meets their high-demand needs.

The standout feature here is the balanced quantity, which sits right in the sweet spot for mid-sized business needs. It provides enough supply to get through a busy quarter without the storage footprint of a massive dozen-pack.
I believe this is a sensible middle ground for those who print more than a home user but don't require industrial-level supplies. The ink quality is generally stable, though you should verify your specific Canon model compatibility upon arrival. It is a solid, middle-of-the-road purchase.
Mid-sized offices find the 5-pack count ideal for quarterly planning.
The ink saturation is described as sufficient for standard paper receipts.

Choosing Between Them
For your Canon P23 DHV, I recommend the COSOB 3-pack as the most practical choice for occasional office use. If you process a high volume of receipts daily, the 12-pack ribbon set is the better financial investment. For those managing a mid-sized operation, the 5-pack option offers a reliable middle ground that keeps your workspace supplied without excess.
Please remember that third-party replacements for the Canon P23 DHV may occasionally exhibit varying print density across different batches. While these options are cost-effective, you should always expect minor differences in ink saturation compared to original manufacturer products. I suggest keeping a spare on hand so you are never caught off guard.
