What Archival Actually Means in Your Pen

That AP seal on your marker? It’s a safety sticker, not a longevity guarantee. This episode breaks down the real chemistry inside an archival-grade pen—from nano-pigment dispersion and acrylic resin binders to pH buffering and the Blue Wool Scale. We explore why "permanent" and "archival" are not the same thing, what the ASTM D6901 standard actually requires, and why nearly half the markers marketed as "archival" fail to meet the standard.
