The ProFab® brand of Calico Bags has been popular with geologists for their fine woven qualities, suitable for retaining fine samples in RC drilling or larger samples when diamond drilling. They have double-stitched seams and a tough, durable drawstring.
What's more, they can be very easily printed and/or barcoded according to your requirements. This makes the transportation from the rig to the laboratory smooth and easy, whilst keeping track of valuable samples every step of the way.
