Rocketbook Beacon Slip-On & Mini

Found the Rocketbook Beacons which came in handy for my one magnetic whiteboard, but i have several Amazon Basics A4 size whiteboard that i have mounted around my home for quick notes or reminders. They measure at 2.8mm thick and what better way to give them a cheap little upgrade to scan and save those notes or reminders! I've created 2 sizes of the Beacons (no text included).Standard 45mm with a 3mm slotMiniaturized version at 25mm with a 3mm slot
