Using a price gun enables speedy price-marking for products and over-pricing for price reductions for sales or special offer items etc. One of the best benefits of the hand-held price gun is its efficiency and mobility i.e. they are small and lightweight and can be easily taken to the location where the products need to be labelled in store. The gun is held in one hand and by pulling the handle upwards the leading-edge of the roll of labels is pulled through the gun by its internal mechanism and thereby partly ejects one sticker out of the 'mouth' of the gun ready to be applied directly onto the product. The used backing paper is automatically separated from the labels as they are dispensed and that generally comes out the rear of the price gun ready for tearing off as required by the operative.
