This muddler is NOT made out of lignum vitae. It is made out of a much lighter, cheaper wood that has been stained the appropriate color. This wood stain is especially problematic in a device generally used for alcohol beverages, as it tends to dissolve in the alcohol.
Unless you're a paint stain drinking enthusiast or don't value your eyesight, I would very seriously recommend avoiding this product.
We love Torani Sugar Free Brown Sugar Cinnamon syrup. It's great in drinks, in oatmeal, over ice cream - anywhere you want a sweet sugar and cinnamon flavor without all the calories. Torani has many great flavors but this is the best of the best.
