The DN4A model features plain, hallmarked Sterling silver and comes standard with a Blackwood pipe chanter silver band. This model adds beaded sterling silver ring caps and silver mouthpiece tube. We exclusively use .925 Sterling silver for this model. Even without engraving the quality shines in the silver mounts. No metal gives off or maintains a sheen like Sterling silver, and these pipes are among the most attractive in the business. A light polishing with a silver cloth once a month will keep this set shining like new in perpetuity.
