Expand your storage: the KS3D Honeycomb Add-on Block
Is your marker collection growing? So can your storage.
Already have your KS3D premium storage block and your marker collection keeps expanding? That's exactly what the honeycomb add-on block is for.
This block is sold on its own, without a base or bar — it's designed to attach directly to your existing premium block, which already provides the necessary support. Simple, efficient, and perfectly integrated.
How does it work?
The add-on block pairs perfectly with your existing premium block. The two blocks form a coherent, stable, and aesthetic unit. Add a second, a third — the modularity is endless.
- 30 additional slots identified by letters, numbers, and symbols
- Sold without base or bar — to be combined with the KS3D premium block
- Pairs perfectly with the KS3D premium block
- Infinitely expandable according to the size of your collection
- Compatible with all cylindrical markers: Posca, brush, gel, calligraphy, acrylic...
- Made in France, on demand
Made in France, piece by piece
Like all KS3D products, this add-on block is printed on demand in our French workshop. Each piece is made especially for you, with care and precision. Allow 3 to 5 business days for 1 block, 5 to 8 days for 2-3 blocks.
