This is the refill for Green Cricket Summer (melon) foaming hand wash. Their 100% natural foaming hand washes clean your hands gently. No need to recycle your bottle straightaway - their foaming hand wash concentrates are easy to use - just fill your counter top bottle to the refill line with water and then add concentrate to the top of the label - that is 2 parts water to 1 part concentrate - and you are all set for another 400 hand washes.
