Design Philosophy

Visual Dimension: Breaking the Boundaries of Display
The "flat display" of square doll bags has inherent blind spots, while the circular bag body achieves "omnidirectional viewing coverage" through its spherical curved surface — whether observed from the front, side, or oblique angle, the doll's expressions and costume details can be fully presented. This design implicitly aligns with the "social attribute of trendy toy collecting": when players use the doll bag as a portable accessory, the circular "dead-angle-free display" allows passers-by to capture the charm of the collection from any angle.
Mechanical Dimension: Upgraded Structural Damage Resistance
The curved surface dispersion effect of the spherical structure enables the uniform decomposition of external impact — compared with the right angles of square bags that are prone to deformation under force, the circular doll bag, when dropped or squeezed, forms a "buffer collaboration" between the toughness of PVC and the spherical curvature, significantly reducing the risk of damage to the internal dolls. Test data shows that under the same impact force, the protection effect of the circular doll bag on internal 15cm cotton dolls is 40% better than that of square bags.
Size Logic: Pragmatism of the Golden Ratio
Based on the mainstream 15cm cotton dolls in the market, the diameter of circular doll bags is usually designed to be 18-20cm (with 2-3cm of buffer space reserved). This size not only ensures the visual beauty of the bag's "full and rounded" shape but also maximizes the use of internal space through the "spherical volume formula" (V=4/3πr³) — it can hold 1 cotton doll + decorative fillers (such as colorful balls, sequins), or 3-4 regular blind boxes.

Precise application of PVC material

Optical-grade transparency: Let trendy toys "show their true colors"
High-transparency PVC particles combined with an anti-yellowing agent formula are selected to achieve a light transmittance of over 95% (close to the 98% light transmittance of glass), while delaying the yellowing problem during long-term use (the anti-yellowing life is 3 times longer than that of ordinary PVC). This material property allows the colors and embroidery details of the dolls to be presented without reservation, and even highlights the "soft luster" of the plush fabric.
Thickness and craftsmanship: The balance between toughness and transparency
Using 0.8-1.2mm thick PVC sheets, formed by high-frequency hot pressing (temperature 160-180℃, pressure 3-5MPa):

The thinness ensures light transmittance, and the thickness guarantees structural strength (the number of bending resistances reaches more than 5000 times, and it is not easy to deform in daily use);
The hot pressing process makes the edges of the bag body "seamlessly connected", smooth and burr-free, avoiding scratches on the dolls or skin.

Synergy between function and aesthetics

Circular zipper system: A solution to the opening and closing problem
A custom arc zipper is adopted, with a "segmented engagement + hidden slider" design to realize 360° surrounding opening and closing:

The zipper teeth are "precisely adapted" to the PVC bag body to avoid jamming;
The slider is embedded in the groove on the edge of the bag body to prevent scratching the internal dolls and maintain the integrity of the appearance.

Portable system: Scene extension for multi-purpose use of one bag
There is a preset metal hanging hole on the top of the bag body, supporting three carrying modes:

Pendant mode: paired with a keychain, it becomes a "trendy toy decoration module" for bags (the weight of a single bag is ≤300g, which is burden-free);
Short chain mode: adapted to a 1cm wide chain, used as a handbag;
Long rope mode: paired with a nylon rope for cross-body travel.

Open up new dimensions for trendy toy storage

The success of the circular doll bag design essentially lies in the deep coupling of "material properties" and "usage scenarios": the high transparency, light weight, and weather resistance of PVC cater to the "display-first" demand for trendy toys; the spatial magic of the circular structure resolves the contradiction between "protection and social interaction". In the future, with the upgrading of PVC formulas (such as degradable PVC) and the iteration of designs (such as interactive opening/closing and intelligent lighting modules), the boundaries of trendy toy storage will continue to expand — but the core logic remains unchanged: to make collecting more free and display more pure.
