WAX BASED PENCILS - Studio Collection colour pencils are wax based pencils with a soft core, which means they are more opaque and perfect for laying down coverage. Due to the amount of pigments in the Studio Collection pencils, they are very rich in colour.
LIGHTFAST: Studio Collection colour pencils have a high lightfast rating based on ASTM testing, which means your work won't fade with time.
BREAK RESISTANT CORES - Studio Collection pencils have high quality binders in the core so they will not break easily under pressure, even when dropped.
