LIHIT LAB. B4 2-hole ring file set of 15. I used these to sort and file the increasing number of textbooks from my cram school. I no longer needed them after using them for a year, so I hope someone else can make use of them. I have removed the labels that were attached to the spines with a label maker before listing them. Please check the condition and understand before considering a purchase. (Please check the spines of the files in the 3rd, 4th, and 5th photos) The following is quoted from the website: ◆ Product Specifications Product number: F-875U Price: 960 yen per book (+ consumption tax) Standard: B4 Type: E type Number of holes: 2 holes Dimensions: 392mm x 36mm x 267mm Capacity: 200 sheets of copy paper Material: Cover/Polypropylene (fabric thickness 1.5mm), Binding/Steel Color: 8 blue ● Ring inner diameter: 25mm * Binding with crimp rivets designed for separate disposal. ◆ Product Features Twist ring that opens with a light twist of one hand.
