I purchased the [KOGU Coffee Tools] Unbreakable French Press for 4400 yen (tax included). I used it once. Includes box and instruction manual. It uses a plastic called "saturated polyester resin (Tritan)," which has the transparency of glass. This material is durable and highly resistant. Compared to other plastics, it is also more scratch-resistant and won't break if dropped. * It may chip if dropped with a strong impact. * Due to the resin molding process, there may be slight scratches, cloudiness on the handle side, and line marks under the spout.
