These clear Heavy-Duty Polythene Bags are perfect for a variety of sampling purposes. When conducting dormouse surveys the bag can be used to safely contain the animals as they are released from nest boxes or nesting tubes. They are great for holding soil, water and other samples when out in the field, and they are also useful for carrying field kit and storing dirty or wet items. Strong and long-lasting, these large bags measure 60 x 90cm.
