This is a great item for barbeques, picnics or the kitchen. The glass bottle holds your favorite oils, sauces, juice, vinegar or marinades. The top has an FDA approved silicone brush that wont fray, melt, shed, lose shape or retain odor and has a heat resistance up to 450 degrees. Just invert the bottle and brush the contents on your meats or veggies while cooking. It has a clear plastic cap with tablespoon and ounce measures that seals tightly to store it right in the fridge. The brush can also be removed to attach to most standard screw-top condiment bottles as well. Holds 2.5 ounces.
