Thank you for viewing this page! This is a tape cutter from Manyu. It's convenient for packing large packages, starting from size 80. I use it myself. The downsides are that it's a bit heavy and requires some technique. It's not suitable for small packages. For more details, please search for "Manyu tape cutter" on YouTube. It's a new, unopened item. I will ship it via Takkyubin (home delivery service). Thank you.
