Chunky blocks deliver the saturated punch of ink with the gestural freedom of pastels. Derwent Inktense XL Blocks contain pigment loads equivalent to eight pencils each, making them remarkably economical for large-scale work or extended sessions. Dry, they produce bold, agile marks across paper, fabric, and other surfaces; activated with water, they transform into permanent, ink-like washes that won't lift once dry.

This permanence matters when layering, subsequent washes won't disturb what's beneath, enabling complex color builds without muddying. The pastel-like format encourages expressive mark-making: drag the broad edge for sweeping color fields, use corners for linear details, or blend dry pigment before activating. Whether working on illustration board or preparing fabric for heat-setting, these blocks handle both controlled application and spontaneous gestural work.

The 6-block set provides essential primaries plus neutrals, Sun Yellow, Bright Blue, Poppy Red, Field Green, Antique White, and Ink Black, enough to explore the medium's capabilities or supplement an existing palette. The 12-block set expands your range without redundancy, adding colors that genuinely extend mixing possibilities rather than filling space with near-duplicates.
