Kallax Compatible Craft Storage

Two ways to shelve WestonBoxes in a Kallax

There are two ways to fit WestonBoxes into an IKEA Kallax cube, and they work quite differently. Our Box Staks are freestanding storage units that happen to fit inside a Kallax. Our Kallax shelf inserts are designed specifically for the Kallax: they fix inside a cubicle and turn it into individual shelves for your boxes. Either way, every box slides out on its own without disturbing the rest.

Box Staks: ten boxes in one Kallax cube

The A5 Box Stak and the Pen & Pencil Box Stak fit side by side inside a single standard Kallax cube, with no wasted space and no gap. Together they give you ten individually accessible storage boxes in one cubicle. Because they're freestanding, you can just as easily use them on a desk, a worktop or any shelf deep enough to take them.

• The right combination: Two A5 Staks won't fit side by side in one cube, and two Pen & Pencil Staks would leave a gap. The A5 + Pen & Pencil pairing is the one that fits exactly.
• Buy it in one go: the IKEA Kallax Compatible Storage Pack combines both Staks, all ten boxes, and handles in a single purchase.
• Already own WestonBoxes boxes? The frame-only versions let you add a Stak without buying boxes you don't need.

Kallax shelf inserts: for A4 and 12x12 boxes

Our Kallax shelf inserts are designed for the IKEA Kallax and no other shelving unit. They aren't freestanding: they stick to the inside walls of a Kallax cubicle with peel-and-stick glue dots, and each box then sits on its own shelf. They're how you shelve the boxes we don't make a Kallax-fitting Stak for.

• A4 inserts, 5 boxes per cube: The A4 Box Stak is too big for a Kallax, so these inserts are the way to shelve A4 Storage Boxes in one. The boxes sit close together, so five black slip-on handles are included to pull each box out smoothly.
• 12x12 inserts, 4 boxes per cube: There's no Stak for the 12x12 Scrapbook Paper Storage Box, so these inserts give your 12x12 boxes individual slide-out shelves. A finger-sized gap between shelves means no handles are needed. Fit a second set of inserts above the first and a single cube holds 8 boxes.
• With or without boxes: Both inserts are available on their own for boxes you already have, or as a pack with boxes included. A4 boxes come in clear, red, pink, purple, blue, green, white or a multicolour mix; 12x12 boxes come in clear.
• Made in Britain: Staks, boxes, handles and Kallax inserts are all made at our factory in Sunbury-on-Thames. The boxes and Stak frames are injection moulded in recyclable polypropylene; the inserts are 3D printed in durable black PETG.
