An extraordinary Danish work! As every proper Danish pipe it's made of a good briar, shows nice grain and has skilfully designed freehand shape. But the most of all we're absolutely amazed with its sense of equilibrium - the pipe can surely balance just on its heel (back side of its bottom). Some signs (such as kind of briar) hint it might be a Karl Erik pipe but we don't have a 100% proof so far.
The pipe markings are "MADE IN \ DENMARK \ MELBY". The length is 13.8 cm (5.43"), bowl's height is 6.3 cm (2.48"). External dimesions of the bowl are 5.7 x 4.0 cm (2.24 x 1.57"), internal diameter is 2.1 cm (0.83"). The depth is 3.2 cm (1.26") and this pipe weights 58 gr. Briar, vulcanite stem, no filter.
