The Rose oil shipping vessel (concum): Certified by the State Laboratory Bulgarian Rose vessels. Concums are available in the sizes 50, 100 and 250 grams; 1, 5 and 15 kg.
Safe transportation of the costly rose oil required good packing. For this purpose, special tinned copper vessels in decorated wooden casing, called concums were designed. The so-called muskals, made of copper or glass, also inserted in poker-worked wooden and sometimes metal casings, were used for smaller quantities. Pictured to the right are the 50 and 100 grams concums.
