Why paper tooth grabs ink
The microscopic roughness of paper holds ink by capillary pull and gives the nib something to bite.
When the purchase is complete, return to the original window. It will refresh.
From the opening
Paper tooth is the fine roughness of fibers and filler at the surface of a sheet. Those tiny valleys pull ink out of a nib by capillary action and keep the wet mark from skating across a slick face. The opening covers fiber valleys pull liquid, capillary force leaves the nib, and sizing limits the sink.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
