The Dr Plumbs 58410 is a traditionally shaped and sized, London made, briar pipe polished with a natural, deep brown tint. As the name gives away it is a smooth, Bulldog shaped Briar bowl with a square shank and curved stem. The length of the stem and thicker briar wall prevents overheating therefore providing a cooler smoother smoke. The Twinbore is named for its distinctive twin bore construction, which features two air channels or "bores" running through the stem. This innovative design promotes a cool and even smoke, ensuring a consistently enjoyable smoking experience. The Twinbore series often offers a variety of shapes and finishes to cater to individual preferences. Whether you prefer a classic billiard or a more unique design, there's likely a Twinbore pipe that suits your taste.
