Office filing solutions designed to make A4 paperwork simple to sort and retrieve. Calm, efficient workspaces suit busy desks and student folders, and the Thboxes A4 File Dividers bring colour-coded tabs to everyday organisation. Are waterproof tabs and useful extras enough to transform a messy binder into a reliable system?

⚡ At a Glance
  • Build Quality: Waterproof PP plastic, resistant to bending and tearing
  • Best for: Office, school and home users who need organised document storage
  • Not ideal for: Users seeking custom-sized tabs or removable, fully detachable dividers

Each pack contains 12 tabbed dividers sized for A4, sold as three packs. Numbered tabs and clear colours make sectioning straightforward.


Faster filing and retrieval – With colourful, numbered 1–12 tabs

Each pack contains 12 pre-numbered tabs, one through twelve, printed on coloured plastic so sections are visually distinct. Tabs measure to suit A4 paper and sit at the edge for immediate visibility.

Find the right folder section quickly by number or colour, reducing search time in busy binders. Clear numbering makes reuse simple across multiple projects or terms.

Stays neat through heavy use – Thanks to waterproof PP material

Made from polypropylene (PP), the dividers resist water ingress, bending and tearing even with frequent handling. The material retains shape and colour under normal office or school use.

Durable tabs survive daily handling and spill-prone environments, so filing stays presentable for longer. The resilience means fewer replacements over time.

Fits most standard ring binders and lever arch files – With 11 punched holes

An 11-hole punch pattern aligns with common A4 binder and lever arch formats, allowing the tabs to sit securely on the binder edge. Hole spacing is designed for standard office and school ring systems.

Slide dividers straight into existing binders without drilling or trimming, making reorganisation fast. Secure fit prevents shifting when flipping through documents.
