Security features of the bags that the S-TEC chamber is fitted to: All openings are secured with metal reversed zip fasteners and the bag is internally stitched. Bags must be fitted with an S-TEC Chamber and sealed with uniquely numbered Harclip seals only. The security bags may be ordered to size and could include an encapsulated window with barcode to uniquely identify the bag.

Please note that chambers are not sold separately from security bags.
