These are NTS orange price-marking labels, 26 x 16 mm, for use in a Judo price marking gun (price labeller). Hand-held labelling guns like the Judo are used in supermarkets, spaza shops, pharmacies, hardware stores and markets to print and apply prices, dates or codes to products quickly; the labels feed from a roll through the gun, which prints the characters set on its bands and applies each label with a squeeze of the trigger. Coloured labels such as these orange ones are commonly used to flag specials, markdowns, expiry dates or different product categories so that staff and customers can spot them at a glance. The box contains 36 units according to the supplier. Make sure your gun takes 26 x 16 mm labels before ordering, as label guns are built for a specific label size.
