Grumbacher Pre-Tested Oils

Pre-Tested is the name of Grumbacher's professional range of oil colors. It's also the name for a philosophy that permeates the way we manufacture all Grumbacher products.

Everything Grumbacher make is tested again and again. Grumbacher time-proven formulas are fine-tuned through independent laboratory test as well as hands-on trial by professional artist. Grumbacher Pre-Tested specify the best ingredients available, putting every new color through a rigorous selection process. Grumbacher test samples of each and every batch of raw material before shipments.
