Technical drawings demand accuracy that ordinary tracing paper can't deliver. Borden & Riley #110M maintains dimensional stability through temperature shifts and humidity changes that cause standard vellums to expand, contract, or buckle. The transparentization process embeds clarity directly into the paper structure rather than relying on fugitive oils that eventually migrate and yellow.

This 16 lb, 100% rag long fiber construction resists cracking when folded repeatedly or handled during revisions. Bright white surface provides crisp contrast for graphite, ink, and pencil work while maintaining transparency for layering and tracing. pH neutral composition ensures archival permanence for contract documents, architectural plans, and technical illustrations that need to last decades without degradation.

The cloth-bound pad format keeps sheets protected and flat between sessions. Engineers and architects working on projects requiring precise registration across multiple overlays rely on this vellum's stability, dimensions stay true whether you're making final presentation drawings or working copies that will see heavy use.
