Sometimes simply referred to as 3D badges. These are a much thicker badge to obtain the 3 D effect. Like most other badges they can be produced in metal only or with the addition of enamel. The enamel is usually supplied without an epoxy coating ( like transparent varnish ) so that it does not screen the 3D effect. The enamel can be matched fairly closely to the Pantone range of colours. They can be supplied in almost any size or shape. Attachments can be a butterfly clasp, brooch, magnetic backing or double sided adhesive backing .
