This unusual puzzle design shows a range of different herbal oils, all neatly displayed in glass bottles. This will be quite a challenging puzzle to complete as the contents of some of the bottles are similar in colour. One for the dedicated puzzler who wants a challenge! The finished puzzle measures 70 x 50cm. Ravensburger adult puzzles are made using "Softclick Premium Puzzle" technology.
