The observed offers
Checked November 4, 2026 on Pentel US direct pages and product feeds: BL77-A black EnerGel RTX medium 0.7 mm was $3.25 per complete pen; LR7-A black 0.7 mm liquid-gel refill was $1.43 per refill; SXS15-G yellow Handy-line S was $1.79 per complete highlighter. These are observed selected variants, not a claim that three different merchants are approved for this site.
Read the unit before ranking
The three prices have different physical denominators. LR7 is documented for BL77, but its lower amount excludes a new pen body. SXS15 is a highlighter and uses SLR3 highlighter refills instead. Ranking all three as interchangeable cheapest writing supplies would ignore the exact purchase requirement. Select the relevant construction and task before using the price.
The separate four-pack observation
A separate current observation showed the yellow SXS15BP4G four-pack at $7.17, or $1.7925 per item. A stale search snippet displayed $5.90, so it is not used as the current price. This small difference illustrates why the selected variant, date and source method belong beside a comparison. It does not establish a historical discount or promise a future sale.
Conditions still to verify
Displayed prices exclude unverified shipping and checkout tax. Add-to-cart and low-stock page signals are not a completed order or guaranteed delivery. Reopen the exact selected listing and confirm destination, quantity and final total. Merchant approval, affiliate terms and real shipping eligibility remain pending; no commission or publisher revenue has been measured.
A source-method note
The current direct product captures and product feeds agreed on the three selected prices. They also provided a newer four-pack value than an older search snippet. We preserve those evidence methods and dates internally. A listing can change after the check, so a link to the official product is part of the reader next step.
No performance ranking follows
The table intentionally has no smoothness, smear, drying or lifetime score. We did not use the products. A pen, a refill and a highlighter can be the appropriate option for different requirements; the lower displayed amount does not select among those tasks. Confirm the needed construction and body relationship before making a cost comparison.
Before you decide
- Keep the exact selected SKU, color and selling unit
- Check current maker scope and the actual seller offer
- Separate your assumptions from measured performance
