LINE INDEX / REFERENCE DESK

The evidence standard

Manufacturer statements,dated official prices and user arithmetic remain separate. BL77 to LR7 and SXS15 highlighter to SLR3 are the two documented finder relationships. A matching point size or brand does not establish another pair. Direct current four-pack price7.17 differs from stale search5.90;the current direct/feed observation is used. We have not tested writing width,drying,smear,paper compatibility,waterproofness or lifespan. Independent stationery/editorial review remains pending.
