The Best Foldable Suitcase- Trunk Collapsible Suitcase by Jollying Review

Hey everyone, it's your girl back with another suitcase review, and this time it's one of my favourite products in recent months.

If you’ve ever dragged a massive, clunky suitcase across cobblestone streets in Europe or through a Tokyo train station during rush hour, you know exactly why I started looking for something different. I’m a frequent flyer (I have no choice, it's for work), and while I’ve made peace with the fact that long-haul trips need a check-in suitcase, I’ve always hated how bulky and inconvenient they are to store at home.

Then I discovered the Jollying Pebble 30’’ Trunk Collapsible Check-In Suitcase and honestly, it’s been an eye-opening experience. It’s not just a large suitcase; it’s a clever, foldable trunk that has completely changed the way I pack, travel, and even how I live between trips.

First Impressions: A Big Suitcase That Doesn’t Eat My Closet

Most 30’’ trunks are enormous! They can swallow 120 liters of clothes and shoes, but when you’re not traveling, they swallow your storage space too. That’s what made the Pebble stand out to me immediately: it collapses down from nearly 17 inches thick to just under 7 inches. That’s a fraction of the size!

Now, when I’m not traveling, I just fold it flat and tuck it behind my wardrobe. No more giant suitcase lurking in the corner of my bedroom. For someone living in a city apartment, this alone feels revolutionary. No more wasted space in my small apartment! 

Built for Long-Haul Travel

I’ve used my Pebble Trunk on two major trips this year: a two-week holiday through Europe and a short adventure in Japan. Both trips really tested it, and it passed with flying colors.

The suitcase holds a lot—120 liters, to be exact. That’s around 30-40 pieces of clothing, plus shoes, toiletries, souvenirs, and even the occasional bottle of wine carefully wrapped in bubble wrap. It handled all of it without a hitch.

The hard shell is aviation-grade polycarbonate but here’s what matters: it’s tough. Mine has survived being tossed around by airline staff in Paris, squeezed onto luggage racks on Japanese bullet trains, and bumped down countless staircases. It still looks almost new, no scratches or dents.

One of the things I didn’t fully appreciate before owning the Pebble Trunk is just how different a trunk-style suitcase feels compared to a standard check-in roller. Traditional check-in bags are usually taller and narrower, which means when you open them, you’re forced to stack things vertically and dig around to find what you need.

A trunk, on the other hand, is shorter and deeper, almost like a chest. The wide opening makes it so much easier to organize and access everything—no more rummaging through layers of clothes just to find that one jacket or pair of jeans. 

It’s like having a portable dresser with you on the road. Another key difference is balance. Normal tall check-in bags can feel a little top-heavy and wobbly, especially when crammed full. The trunk shape spreads the weight more evenly, which I noticed makes it feel sturdier and easier to maneuver through airports and train stations. 

On my trips, I didn’t once feel like it was going to tip over while I was wheeling it. That sense of stability, combined with the collapsible design, makes the Pebble Trunk stand out in a way regular check-in luggage just can’t match.

Trip 1: From Paris to Rome

On my Europe trip, I had six flights in total, hopping between Paris, Rome, and Madrid. Normally, that many transfers means my suitcase would come back with cracked corners and scuffed wheels. Not this time.

I loved how smooth the wheels were...even fully loaded, it glided across airport floors without the rattling noise I was used to with my old luggage. When I had to rush through Charles de Gaulle to make a connection, I felt like I was pushing air, not dragging 20 kilos of clothes.

The TSA-approved lock also saved me at customs in Rome. Instead of fumbling with padlocks or worrying about broken zippers, the security officer just clicked it open, inspected quickly, and handed it back without fuss. 

Trip 2: Japan (Navigating Trains and Tiny Hotels)

Japan is wonderful, but traveling with big luggage there can be stressful. Trains are packed, hotel rooms are compact, and storage space is minimal. This is where the suitcase really shined.

Even though it’s a full 30’’ trunk, the foldable feature meant that when I reached my hotel in Tokyo, I could unpack, collapse the suitcase, and slide it neatly under the bed. Suddenly, my room felt spacious instead of cramped. Honestly, that made my stay so much more comfortable.

I was also grateful for the suitcase’s slim, upright profile. It fit into the designated luggage space perfectly, and the wheels made rolling it through the station so much easier than wrestling with a traditional, heavier trunk.

Another highlight was buying souvenirs with this suitcase. I usually run out of space, but the Pebble has this 1:9 opening design that gives it about 20% more storage space than other trunks. That little design tweak made a big difference. I was able to fit everything, carefully packed, without sitting on the suitcase to zip it up. It felt like the bag was designed with shoppers in mind.

What Makes It Stand Out

• Foldable design: Stores flat at home, saving space.
• Huge 120L capacity: Enough for a 2–3 week trip without compromise.
• Durable hard shell: Withstands airline handling, cobblestones, and rough travel.
• Silent spinner wheels: Maneuvers smoothly, even fully loaded.
• TSA-approved lock and YKK zippers: Security without stress.
• Lightweight for its size: At 6kg, it’s surprisingly easy to manage.

Price vs. Value

The suitcase costs $389 (similar range to the 20’’ Pebble) and honestly isn’t cheap. But when you factor in its durability, the IF Design Award, and the sheer convenience of foldability, it feels justified. I used to think, “a suitcase is just a suitcase.” Now I see it as an investment that actually improves my travel experience.

And because it collapses, I don’t resent owning a big suitcase anymore. I don’t feel like it’s stealing space in my life between trips. That makes the cost feel even more worth it.

This suitcase is suitable for people who: 

• Travel long-haul often, whether for holidays or work

• Need lots of storage without wanting multiple bags

• Live in a small apartment and hate bulky suitcases lying around

• Care about durability and design

Final Thoughts

I’ve taken the Jollying Pebble 30’’ Collapsible Trunk across Europe and Japan this year, and I honestly can’t imagine going back to a regular suitcase. It’s strong enough for airline handling, roomy enough for long-haul packing, smooth enough to glide through stations, and clever enough to fold away at home.

Travel already has enough stress built in, e.g. delays, connections, navigating foreign cities. My luggage shouldn’t add to that, and with the Pebble, it never does. Instead, it feels like a reliable travel companion that just makes everything easier.

⭐️⭐️⭐️⭐️⭐️ (5/5)
