Pineberry is a creamy translucent yellow that turns a bright pink under CFL reactive lights. Like Boro Batch's other CFL colors, Pineberry works well in a neutral flame and is super easy to work. When working with Pineberry it is recommended to be used in thicker applications to see the best color shifts. Boro Batch Thins range from approximately 3.5mm - 5mm in diameter.
