XL Packaging's luxury PU leather jewelry boxes are crafted with exquisite craftsmanship and high-end design, serving as a packaging solution that combines protection and aesthetic value for necklaces, bracelets, earrings, and other jewelry. Below is a detailed explanation covering material innovation, functional design, customization flexibility, and practical scenarios:

I. Materials & Craftsmanship: Fusion of Technology and Aesthetics
Surface Material
High-quality food-grade PU leather (Polyurethane Leather) is used, with its surface mimicking natural leather textures through micro-embossing technology, offering a (soft touch) and scratch resistance. Compared to traditional PVC leather, PU leather contains no heavy metals or harmful chemicals, complying with EU REACH environmental standards and making it safer for contact with sensitive skin. For example, the classic black model features a matte coating paired with matching color stitching, presenting understated luxury; the burgundy version uses pearlescent PU leather, showcasing a unique luster under light refraction.

Internal Structure
Cushioning Lining: The box comes standard with a high-density EVA foam layer, covered with velvet or silk-like fabric. Grooves can be cut according to jewelry shapes to ensure no friction on delicate parts like necklace chains or earring posts.
Reinforced Design: The box body uses 2mm thick MDF (Medium Density Fiberboard) as the frame, with edges seamlessly bonded to PU leather via ultrasonic welding technology. Its compressive strength exceeds 50kg, effectively resisting collisions during transportation.
Secure Latch: The magnetic closure system adopts neodymium-iron-boron strong magnets with a suction force of 20N, paired with a hidden metal latch to prevent accidental opening of the lid during shaking.

Innovative Craftsmanship
Hot Pressing Forming: Through 120℃ high-temperature molding, seamless transitions between box curves and edges are achieved, avoiding glue failure risks from traditional adhesive bonding.
Antibacterial Treatment: Nano-silver ions are added to the lining material, inhibiting 99.9% of mold and bacterial growth—ideal for jewelry storage in humid southern regions.
II. Functional Design: Integration of Humanization and Intelligence

Modular Storage System
Layered Structure: Two designs are available: double-layer drawer-style (e.g., L24×W17×H35cm model) and flip-top + side-pull box. The upper layer can hold daily-worn earrings and rings, while the lower drawer stores necklaces or watches, preventing tangling.
Detachable Partitions: Internal partitions use ABS plastic snap connections, allowing users to freely adjust compartments based on jewelry size. For example, long partitions can be combined into a dedicated slot for bracelets.
Smart Additional Features
LED Lighting System: Optional hidden LED strips, controlled by a touch switch, automatically light up when the lid is opened—enhancing jewelry display effects (e.g., creating ambiance for proposal scenarios).
Mirror Design: A scratch-resistant glass mirror (3mm thick) is inlaid inside the lid, convenient for users to check details when wearing earrings. It also supports custom etched brand logos.
Portability Optimization
Non-Slip Base: 3M anti-slip silicone pads are attached to the bottom, preventing the box from sliding on smooth surfaces and reducing noise during opening/closing.
Magnetic Handle: An optional detachable leather handle is available, connected to the box via magnetic buckles for easy carrying at exhibitions or as gift packaging.

III. Customization Services: From Brand Identity to Scenario-Based Design

Basic Customization Options
Size Adaptation: Full-size customization is supported, ranging from 5cm×5cm (ring boxes) to 30cm×20cm (multi-layer storage boxes), with a tolerance of ±0.5mm.
Printing Techniques: Three techniques are offered—gold/silver stamping, UV printing, and laser engraving—allowing brand logos, product QR codes, or custom patterns on the box surface. For instance, a jewelry brand used gold stamping to print its emblem on the lid, paired with a matching lining, enhancing overall visual consistency by 30%.

In-Depth Scenario-Based Design
Wedding-Exclusive Models: Red PU leather with gold embossing is used, with a heart-shaped jewelry holder inside. The lid is stamped with the couple’s initials, serving as exclusive packaging for wedding rings.
Travel-Friendly Models: Foldable structures are designed, expanding into multi-layer storage boxes and folding to a thickness of only 3cm—easily fitting into carry-on luggage. Elastic straps inside secure necklaces to prevent shaking.

Recyclable Packaging: Reusable metal-latched gift boxes are available. Customers can apply for empty box
