Sticky notes in a cube are an indispensable accessory on every desk. The notes are ideal for writing lists or taking notes. They feature attractive, bold colors that immediately attract attention and ensure that you never forget your notes. You can write down important information on them and stick them in a visible place. The notes peel off easily and leave no traces of glue.

It is important to know

When choosing a 3M Post-it 2051-U ULTRA mini cube, it's important to understand how its format, quantity and material fit into your workflow. It's especially important to consider whether the 51 x 51 mm 400-sheet mini cube is suitable for the type of marking you need and how it will complement your existing document organization system.

• The small format allows for discreet marking, but due to its limited size, it is not suitable for longer notes or larger annotations.
• Paper material allows writing with pencils, pens or markers, but is less resistant to tearing with frequent use or when transferring documents between departments.
• The quantity of 400 sheets in one cube is practical for teams or multiple uses, but may be too large for smaller offices or individual use if marking is not done regularly.

In practice

🟢 Tagging contracts or project folders

Due to its compact size and writing capabilities, it is very suitable for quickly marking and separating different projects or documents.

🟢 Temporarily mark pages or important places in documents

Sticky notes allow for temporary marking without permanent marks, suitable for projects that require frequent changes.

🟡 Archiving or permanent indexing of documents

Suitable with limitations: paper material is less resistant compared to plastic indexes, so there is a greater chance of wear and tear with very frequent use or archiving.

🟡 Organizing large amounts of documents in the team

Suitable with limitations: the larger amount of slips suits offices with multiple users, but the small format does not allow for longer notes or greater visibility in thick folders.
