Know What’s Inside

Why This Works

Common questions about capacity, access and durability — answered with useful detail.

What fits in a 66L storage box?

About 8 folded sweaters, ~6 hoodies, or ~16 pairs of jeans — a typical mixed seasonal load is 20–24 folded pieces. Full breakdown in our guide: What Fits in a 66L Storage Box? (Estimated from the 50 × 40 × 33 cm interior.)

What are the exact dimensions?

50 × 40 × 33 cm (19.7 × 15.7 × 13.0 in).

What does “dual-window” mean?

Two access points: load from the top, or reach items from the front window without unpacking everything above them — useful when boxes sit on shelves or stacked in a closet.

Will it stay upright when full?

Yes — the 5mm internal steel frame keeps the box upright, stable and neatly shaped as it fills, and supports up to 50 kg (110 lbs). When empty, the box folds flat for compact storage.

66L or 100L — which size do I need?

Choose the 66L for clothing and everyday seasonal storage; choose the 100L XL for bulky bedding (comforters, blankets, pillows). The 100L holds ≈52% more volume.

How do I label it?

The clear side label pocket holds a category card so you can identify each box at a glance.

Do Kinfold organizers arrive folded or assembled?

Every Kinfold organizer ships folded flat to save packaging space. There’s no assembly — just unfold it, and the internal steel frame pops the box into its full shape in seconds. When you’re not using it, fold it flat again for compact storage.

What is the Skystone™ material?

Skystone™ is our signature cotton-linen fabric with a finely textured weave and a soft, neutral look that blends naturally into bedrooms and closets. It is waterproof and dust-resistant, fully washable, made from natural eco-friendly fibers that are biodegradable, and completely odorless out of the box.

Are the steel frames removable?

No — the frame is sewn into the structure so the box keeps its shape even when fully loaded. The 26L organizer uses a 4mm frame; the 66L and 100L boxes use a 5mm frame.

How fast is shipping?

Orders ship from our California warehouse on the next business day and typically arrive within 5–8 business days in major US cities (longer for remote areas). We ship within the United States via UPS, FedEx, or USPS.

Can I cancel or change my order?

You can cancel within 1 hour (60 minutes) of placing your order. After that, once processing or shipping has begun, you may be responsible for any return shipping fees. Delivery addresses cannot be changed once an order is in transit.

How much weight can the boxes hold?

The 66L and 100L boxes are built on a 5mm steel frame that supports up to 50 kg (110 lbs). The 26L organizer uses a lighter 4mm frame designed for everyday clothing rather than heavy loads. All boxes fold flat when empty.

Finally, a box that fits my closet shelf

I bought this for my sweaters and hoodies and it fits perfectly on my closet shelf. The dual windows make it so easy to see what's inside without opening everything. Sturdy build, smooth zippers — very happy with this purchase.

★★★★★

Perfect for my wardrobe overflow

My apartment closet is tiny, so I keep this box on top of the wardrobe for out-of-season clothes. It's roomy, looks neat, and the dual windows let me spot things fast. Great value for the price.

★★★★★

Great box — wish there were more colors

Really good quality and the size is perfect for folded jeans and sweaters. Zippers feel durable. Only downside is the color options are limited, so it's hard to match my closet. Would still recommend.

★★★★★

Seasonal clothes problem solved

Every spring and fall I used to drag out plastic bins. This 66L box holds all my winter sweaters plus a few pairs of jeans, and it looks much cleaner than my old bins. The handles make it easy to move around.

★★★★★

Holds way more than I expected

I fit about 12 sweaters and 5 pairs of jeans in here, which was more than I thought possible. The clear windows are a lifesaver when I'm looking for a specific color. Solid frame — it doesn't collapse when stacked.

★★★★★

Room for all my winter sweaters

I packed away 10 sweaters, 3 hoodies and a stack of jeans in this box and it closed easily. The see-through windows are perfect for spotting colors without digging. Sturdy enough to stack two high.

★★★★★

Closet clutter, gone

My closet shelf finally looks organized. This box holds way more than it looks like it should, and the handles make it easy to pull down from the top shelf. Very well built.

★★★★★

Great box, slightly stiff zipper at first

Quality feels premium and it holds all my seasonal clothes. The zipper was a bit stiff for the first couple of uses but loosened up quickly. Otherwise perfect.

★★★★★

Best storage box I've owned

I've tried plastic bins and fabric cubes — this is better than both. The frame keeps its shape, the dual windows actually work well, and it looks clean in my closet.

★★★★★

Perfect for apartment living

Living in a small apartment means maximizing closet space. This box sits neatly on my shelf and holds everything I need for off-season. Love the clear windows.

★★★★★

Sweaters finally have a home

My sweaters used to pile up on the chair — now they're all in this box, visible through the window, easy to grab. It's sturdy and the size is just right for a shelf.

★★★★★

Worth every penny

Solid construction, smooth zippers, and it looks great on my closet shelf. I bought one for my sweaters and immediately ordered a second for blankets.

★★★★★

Holds a surprising amount

I fit 8 hoodies and 6 pairs of jeans in here with room to spare. The dual windows make it easy to see what's inside, and the structure doesn't sag even when full.

★★★★★

Nice box, wish it were a bit deeper

Great quality and looks tidy in my closet. It fits my folded tees and hoodies well, though I wish the depth were slightly larger for bulky knits.
