Hi. We need to do a prototype run for a new product we are developing. It is to make custom collars to house tracking units for wild dogs. The material we require is: 1) 20m of 2" wide (50mm)x2mm thick and 2) 20m of 2" wide (50mm)x3mm thick. The Collar material must not be harmful to the animal. If will be sewn together. Please recommend a suitable BioThane product. Also, what is the minimum order quantity and how soon can we get it to South Africa. Please forward a quote. Thanks. Mark
