Thank you for viewing! This item was purchased by my mother decades ago, but she never used it, so I am selling it. The year of manufacture is unknown. When held up to the light, there are about three barely visible spots on the front and one on the back, but they are hardly noticeable. Although there is no certificate of authenticity, the instruction manual for the bamboo handle will be included in the inner pocket. The bag has a few stains, but I will include it. It has been stored in a dark place, but I have carefully wiped it down with a towel just in case. Please refrain from purchasing if you are sensitive to used items, as it is not a new, unopened product.
