My Review of the JMBricklayer Jellyfish Set: A Relaxing Dive Beneath t

I first discovered JMBricklayer through their Steampunk Marble Run (70003) on Kickstarter—a beautifully engineered set that quickly became one of my all-time favorites.
The attention to detail, the thoughtful design, and the joy of watching those marbles race through the gears left a strong impression. It wasn’t just a building kit—it was an experience.So when I came across their new Jellyfish Building Set (70010), I didn’t hesitate.

With 1,310 pieces, glowing light effects, and an elegant ocean-inspired design, it felt like the perfect way to bring a bit of calm into my space.
I wasn’t sure if I could handle the complexity at first, but after building it, I can say this set is a true hidden gem.

The Design – A Living Sculpture from the Ocean’s Heart

This isn’t just a regular sea animal toy—it’s a miniature underwater world full of surprises. The star, of course, is the jellyfish, whose 360° rotating tentacles move with lifelike fluidity. Combined with a soft, glowing blue light, it almost feels alive—like you’ve captured a real sea creature and placed it gently in your room.

But the real magic is in the details. Surrounding the jellyfish are tiny sea creatures: a hidden crab, a colorful fish, glowing corals, gently swaying seaweed, and even a little treasure chest resting on the seafloor. The miniature aquarium base brings these touches to life, turning the whole scene into an elegant, glowing habitat. It’s so immersive that once the build is complete and the lights are on, it’s like moving an entire ocean scene into your home.

And despite all this detail, the final structure is about the size of a small desk lamp—perfectly sized for a nightstand, display shelf, or office corner.

Building It – Simple Enough to Relax, Detailed Enough to Satisfy

I won’t lie—1310 pieces sound like a lot. But I found the instructions surprisingly beginner-friendly. As someone not usually into complex builds, I appreciated the clear manual, included assembly tools, and the way the structure unfolds step by step. It felt more like a calming puzzle than a challenge.

Piece by piece, I saw the jellyfish head come to life, followed by the detailed sea base. Every small part added up to something beautiful, and building it felt like a meditation. The 3.5-star difficulty is just right: satisfying without being overwhelming.

Features – Not Just Pretty, But Practical Too

What really sets the JMBricklayer Jellyfish Building Set apart is its dual function: it’s both an aesthetic decor piece and a soft ambient night lamp. The built-in light system gently illuminates the base and the jellyfish body. As the tentacles rotate, the changing shadows and glow create a peaceful underwater effect.

This makes it great for more than just display—it’s a functional animal night lamp that fits perfectly in an office set, a child’s room, or a cozy living room nook.

Brand and Service – Peace of Mind, Guaranteed

One thing I love about JMBricklayer is how much they value their customers. When I ordered the set, I felt reassured by the 30-day free trial and 100% refund policy. Even better—they’ll replace any missing parts or resend the manual if needed. They actually listen to customer feedback and are always working to improve. That kind of service makes a huge difference.

For $69.99, the value is unmatched. The quality, the design, the immersive experience—it’s all well worth it. I genuinely believe you're getting a lot more than just a building kit. You're getting a piece of art that brings the ocean to life in your home.

It’s no surprise that JMBricklayer has earned the trust of over 1,700 backers across 20+ countries on Kickstarter and Indiegogo.
From crowdfunding believers to everyday builders, the community keeps growing—and so does the love for hands-on, meaningful design.
