Thank you for viewing. I am a non-smoker and do not have any pets. It's been about 10 years since I purchased this, and it has been stored in a dark place. I took photos for this listing, and the hole punching is still smooth. *I am borrowing the MUJI tag because MUJI sells a similar item. Here is the description: ◉ Instead of a shredder, this is for privacy protection by punching holes. Just use it like a stapler to punch out the addresses on direct mail. I haven't used it much, so there are no noticeable scratches or stains, but it is a used item. Please understand this before purchasing. ● A new method for privacy protection! Easily cut out the lines you're concerned about by punching 7 holes simultaneously on the addresses of direct mail, amounts on invoices, etc. ● Easy to use, just like a punch. Compact size that can be stored in a drawer. ● The cut-out waste is 6mm in diameter. Eliminates the worry of information leakage from the waste. Also eliminates the unpleasant feeling of increased waste volume when shredding. This is a completely new stationery item born from a different concept than a shredder, specifically designed for cutting out only the parts you don't want others to see, such as addresses, amounts on invoices, and card numbers, when disposing of direct mail and invoices. It's simple: it punches 7 holes like a punch. A slim, red stapler design, convenient for home or office use. - Color: Red - Material: Plastic and metal - Design: Slim and compact - Function: Hole punch
