This is a Swingline hole punch, suitable for both 3-hole and 2-hole punching. The hole positions are adjustable. Product Name: Swingline Precision Pro Desktop 3 Hole Punch Features: Can punch up to 10 sheets of paper at once. Capable of 2-hole or 3-hole punching, with an adjustable punch head. The paper chip tray slides open easily for convenient disposal. Uses: Suitable for organizing documents in general offices and homes. The image shows A4-sized paper underneath, suggesting it supports punching holes in A4-sized documents. Purchased about 4 years ago and used for organizing A4 paper documents for one season. I will be listing it for sale as I no longer plan to use it. Would anyone be interested? It will be bubble-wrapped and shipped via Mercari delivery. Thank you for looking. #HolePunch #Punch
