Large Moving Boxes 20'' x 20'' x 15'' (Pack of 6), Corrugated Cardboard Boxes for Packing, Shipping & Moving

I recently used the UBOXES Large Moving Boxes (20" x 20" x 15", Pack of 12) for a big move, and they exceeded my expectations! These boxes are exactly what you want when you need durable, reliable packing supplies. 📦 Great Size: The 20" x 20" x 15" dimensions are super versatile — roomy enough for bulky items like blankets, pillows, clothing, and kitchen gear, but not so large that they get overly heavy or awkward to lift. 💪 Sturdy Construction: The cardboard is thick and solid, which gave me confidence during packing and moving. Even when stacked, these boxes held their shape well and didn’t collapse under weight. 🛠️ Easy to Use: They arrived flat and clean, and popped together quickly. I was able to tape them up in minutes and start packing right away. 📍 12 Boxes is a Great Pack: This size pack was perfect for my whole house — everything from living room to bedroom got packed up efficiently. It was enough without being excessive. ⭐ Durable & Reliable: These boxes stood up to a long day of moving and rough handling without tearing or buckling. Overall, the UBOXES Large Moving Boxes are a reliable, good‑quality choice for moving or storage. They made packing so much easier — highly recommend! 📦✨

TL;DR: Good value for shipping bulky light items. Easy to build and tape. Feels underbuilt for dense loads, so I recommend you reinforce and keep weights conservative. I bought this 12 pack for outbound shipping, not moving, and the size proved good enough for soft goods and “irregular” (for lack of better terms) items. At 20 by 20 by 15 inches you get generous volume without creating a back problem for the carrier. Assembly is straightforward. Scores are clean, flaps meet square, and standard packing tape bonds without curling. Once taped, the boxes handle light freight reliably. Strength is consistent with standard single wall. That is fine for things you may have like pillows, apparel, plush, bedding, and lightweight plastics. It is less fine for dense merchandise such as books, small appliances with sharp edges, hardware, and canned goods. Bottom panels begin to bow when you push weight toward the mid 30s, and corners show compression if heavier cartons ride on top during transit. I did not see glue seam failures, but I would not trust this size and wall for conveyor abuse with heavy contents. For shipping, one practical note about cost control. A box this large often triggers dimensional weight with major carriers. That means you pay for the space more than the scale weight on many services. If you are sending light items, the economics make sense. If you are sending dense items, a smaller footprint box will usually reduce both damage risk and postage. What worked well • Value per box is strong for volume shipping of light goods • Easy, repeatable assembly and square flaps that close flush • Tape adhesion is good with 2.2 to 2.7 mil acrylic or hot melt • Interior is clean and low on box dust, which helps when packing textiles Where it struggled in real use • Single wall flexes with dense loads and long conveyor runs • Corners dent when stacked under heavier cartons • Not ideal for heavy or fragile freight unless you add structure Simple upgrades that improved outcomes 1. H tape the bottom and the top, then add one crosswise strip on the bottom. 2. Run a strip of tape inside along the bottom seam to reduce sag. 3. Add corner posts or folded scrap corrugate for hard edged items. 4. Use a 3 inch tape for better edge coverage and fewer peel ups. 5. Cap ship weights around 30 to 35 lb for this size if you want consistent delivery quality. 6. For fragile or dense goods, double box with a smaller inner carton and at least two inches of void fill. Bottom line For outbound shipments of bulky light products these boxes are a cost effective, time saving choice. They are not a strength monster, so treat them like standard single wall. Reinforce the bottoms, protect the corners, and keep weights modest. Pair them with smaller heavy duty boxes when the contents are dense or fragile. Used that way, they do exactly what you want without inflating your packaging budget. Thanks for reading!! (Assuming you did)

What can I say? I ordered these online because I’m busy and I needed to get boxes for a move. They came super fast. The quality is excellent. They were very sturdy and excellent quality boxes. I bought many different sizes from small to x large. They were packaged very well and the next time I move, I will be ordering the same thing. Great service quick delivery.

I received these moving boxes from Amazon just in time for me to get ready and starting to pack all my items for moving and I must say these are excellent boxes they can hold so much stuffs inside them that I couldn’t believe with all my belongings that I got could be fits all inside these boxes because of how tight packed I put my items in each one them as with insulated to avoid just in case they could be moving around and got damaged by the movers, everything arrived in my new place were in perfect condition due to their strong and well made these boxes.

These boxes are slightly shorter and wider than Home Depot "Medium" boxes. I wouldn't call them "Large", by any means. However, that means they are harder to hold onto. A standard medium box can usually be easily held by one person. I have long arms, and this box is hard to hold by myself without at least slightly squishing the contents. Structurally, however, they stood up fine for me. By the end of the move, they are a tad bit flimsy, but I'd comfortably reuse them about one more time before needing to toss them. Overall, the box is alright. Plan to need someone to help you carry each box, and be aware that structurally they'll only last you just long enough for the move.

I had so many boxes left over afterwards, sturdy and thick. Great value for the price as well.

These boxes were very sturdy and recommend for moving. Cheaper than local stores.

Strong and sturdy. Easy to assemble

Exactly what I needed to move. Boxes are good quality and really big, I didn’t even end up using all 6

ممتازة جدا

Las cajas cumplen con el cometido son fuertes y resisten bastante el peso interno, solo debe asegurarse uno de encintar o cerrar de manera correcta. las recomiendo incluso para empacar articulos varios sino es especifico de mudanza sino para almacenaje

Me encantaron las piezas y el embalaje. Justo lo que necesitaba.

جودتها حلوة وحجمها كبير بس اللي وصلني 6 صناديق فقط مو 12
