Adhesive Stickers. Bongo specialises in the manufacture and design of permanent and removable adhesive stickers, labels and decals for every kind of use. Stickers are an economical promotional product that convey strong messages for advertising. We manufacture custom printed paper, vinyl, electrostatic, reflective, metallic, sticker sheets and weatherproof vinyl stickers to suit any application. Our electrostatic vinyl stickers are made with a cling material which successfully adheres to glass and smooth objects by static electricity as opposed to standard adhesive. These stickers are used for short term outdoor or indoor promotions. The stickers can be supplied to glass, enamel and any high gloss shiny surface.
