These 3M Post-it have a compact size of 47.6mm x 47.6mm. They are ideal for short notes, phone numbers and reminders. The super sticky notes have an adhesive edge that is more powerful than standard Post-its; ideal for notes you want to keep hanging around for a long time. These note sheets also stick better to difficult surfaces. The package contains 12 blocks, each with 90 Post-its. The coloured notes with colour set 'Soulful' have pastel colours (lilac, pink, purple, blue and mint green).
