Thank you for viewing. I purchased this from Yoshio Kobo's catalog a long time ago, intending to make Danish pastries at home, but I never used it and it has been stored for a long time. It is new and unused, but as you can see in the photos, the bag has deteriorated over time and has some tears. I would be happy if someone who is opening a bakery or someone who can use it at home would like it. It is for commercial use, so it is sturdier than cheap pie rollers, and the blades are sharp and very easy to handle. The blade diameter is 4.5cm, and the width when expanded is 48.4cm. Made of stainless steel. It is new, so I haven't opened the bag, but it will be used as shown in photo 7 (reference). If you have any questions, I am a baker, so I will respond if you leave a comment. Thank you.
