Princeton Neptune Synthetic Squirrel Quill #4

Neptune is Princeton's thirstiest brush ever, delivering loads of glaze or slip to your work. Featuring the latest synthetic fiber technology, Neptune's multiple-diameter filaments are configured to replicate the smooth feel of natural Squirrel, with enhanced snap and resilient strength. Experts in natural hair have been incredulous that the Neptune brush fibers are actually synthetic. Almost 20 years ago, Princeton gave artists a synthetic version of sable that was almost equal to fine Kolinsky. Today, it's still the standard for performance among its rivals. When Princeton set out to create a synthetic version of Squirrel, the company developed a brush that may actually outperform the natural version.
