The Mini Mechanical Jellyfish is a handcrafted kinetic desk sculpture featuring a pure copper jellyfish bell, multi-layer metal-painted tentacles, and a crystal-clear glass dome, mounted on a premium walnut wood base. Dimensions: 15cm H × 8cm W / 5.9" × 3.1". Built-in lithium battery with 48-hour runtime, TYPE-C charging (3-hour charge time), and 5-minute auto-stop with tap-to-wake functionality.

Designed for ocean lovers, collectors of kinetic art, and anyone who wants a living, moving desk sculpture that brings the ethereal grace of a jellyfish in motion to their workspace — under a crystal-clear glass dome that makes it feel like a private aquarium.

About This Item

• Pure copper jellyfish bell. The bell (body) of the jellyfish is crafted from pure copper — warm, lustrous, and naturally antimicrobial. The copper develops a subtle patina over time, adding character and depth to the piece.
• Multi-material tentacles. The tentacles are crafted from stainless steel, aluminum alloy, and ABS with multi-layer metal paint — creating a layered, translucent visual effect that mimics the delicate trailing tentacles of a real jellyfish in motion.
• 5-minute auto-stop + tap-to-wake. The sculpture automatically stops after 5 minutes to conserve battery. A gentle tap on the glass dome wakes it instantly — no buttons, no switches, just touch.
• 48-hour battery life, TYPE-C charging. The built-in lithium battery delivers 48 hours of runtime per 3-hour TYPE-C charge — weeks of daily use between charges.
• Crystal-clear glass dome on walnut base. The glass dome creates a private display environment that protects the sculpture and enhances the visual drama. The premium walnut wood base provides warm, natural contrast to the copper and glass.
• Free custom engraving (up to 8 characters). Names, initials, or dates engraved on the walnut base.

FAQ

Q: How do I wake it after auto-stop?
A: A gentle tap on the glass dome activates tap-to-wake — the jellyfish resumes motion immediately. No buttons or switches required.

Q: How long does a charge last?
A: 48 hours of runtime per 3-hour TYPE-C charge. For typical desk use (a few hours per day), a single charge lasts several weeks.

Q: Will the copper develop patina?
A: Yes. Pure copper naturally develops a warm patina over time with exposure to air. This is a characteristic of authentic copper and adds character to the piece. The glass dome slows the patina process by limiting air exposure.

Q: Does this make a good gift?
A: Yes. One of the most distinctive kinetic desk gifts available — popular for ocean lovers, collectors, and anyone who appreciates extraordinary craftsmanship. Free engraving up to 8 characters on the walnut base. Free shipping on orders over $59.
