It helps colors stay fresh from the palette and allows easy rework, making it suitable for artists who frequently refine or adjust strokes.

Buying Guide: Key Purchase Considerations
What finish do you want? Gloss finishes enhance color saturation and depth, while satin finishes reduce glare and emphasize brushwork. UV archival options provide longer color stability for works exposed to light. For sensitive studios, non-toxic or low-VOC formulas reduce exposure during application.
