Frequently Asked Questions
Q: Can the internal laser engraving system place two separate portraits side-by-side inside this heart shape crystal?
A: Yes — our production line uses high-density sub-surface laser arrays paired with advanced conversion software. We can cleanly isolate and compile two individual portrait faces from standard photos, suspending them symmetrically side-by-side inside the heart core.
Q: How do users activate the multi-color RGB LED lighting cycle on this heart charm?
A: The token features a premium mechanical twist mechanism. By giving the stainless steel top cap housing the button cells a slight clockwise turn, the circuit connects and starts an automated, rotating seven-color gradient loop that illuminates the 3D couple portrait inside.
Q: Can we engrave custom text, like a wedding date or initials, onto the crystal base area?
A: Yes — our laser software can place a 3D portrait in the center while engraving custom dates, initials, or small heart icons right behind or beneath the image. Sourcing buyers can coordinate graphic layouts directly through our factory Customized Services terminal.
Q: What type of batteries power this heart crystal keychain, and are they easy to replace?
A: Every token comes pre-loaded with standard, lightweight button cell battery disks. When the power eventually drains, simply unscrew the top metal connection block, lift out the spent cell disks, and drop fresh replacements into the chamber to keep the light working perfectly.
Q: Will the heart-shaped crystal glass fade, cloud, or turn yellow after years of pocket use?
A: No — because we use top-tier optical-grade K9 crystal instead of cheap acrylic resins, the body retains perfect clarity over decades of use. Since the laser point map resides completely inside the glass matrix, it cannot be scratched or worn away by everyday keys.
Q: Is this pocket-sized heart keychain safe for wedding favor distribution or children's gift sets?
A: Yes — the robust crystal body contains zero liquid components, hazardous chemical materials, or external wires. The safe, low-draw button batteries are securely locked behind a stainless steel screw cap, creating a durable and highly stable promotional item.
Q: What file formats are required when submitting couples photographs for high-volume custom runs?
A: We accept high-resolution JPEG, PNG, or standard vector files (.AI, .EPS, .DXF) through our B2B portal. Providing clear, crisp images helps our technical division build a detailed, lifelike 3D point map inside the glass matrix.
Q: What packaging standard is used to safeguard these heart-shaped crystal items during international ocean transit?
A: Every finished keychain is nestled inside a custom foam cutout within an independent presentation gift box. These display cases are packed into thick master shipping cartons, ensuring total protection against drops and shifting during global distribution.
Q: Can we request custom silk ribbon bow-ties or custom text printing on the outer gift boxes for weddings?
A: Yes — for bulk institutional orders or large wedding shipments, we can coordinate custom screen printing, silver foil stamping, or specialized box color schemes to match your theme. Speak with our sales division to align your custom packaging requirements.
Q: What is the average manufacturing turnaround time for a bulk custom order during peak holiday gift seasons?
A: After the digital vector proofs are approved by the client, standard custom crystal processing and assembly typically takes 7 to 12 business days. Shipping schedules vary based on air or ocean options chosen for your target logistics destination.
