Numbered Certificates of Authenticity: A Guide
Everything below is written for collectors who are weighing Numbered Certificates of Authenticity: A Guide — the numbers, the trade-offs and the details that decide whether the piece still looks right three years in.
Armour You Can Pose
The LIN YUANZHE 1/4-scale articulated bust carries articulated armour panels that move on their intended axis and hold position. The pose is part of the display, not a fixed mould, which is what separates it from a static bust and is the reason the piece rewards a shelf you walk past from several angles.
Resin vs Polystone vs PVC
PVC is light and flexible and used for mass-market figures; polystone and resin are rigid and heavy and used for premium busts. The weight in the hand is the fastest field check: a polystone or resin composite feels dense and cold, while a hollow PVC recast feels light and warm for its volume.
Power Source Notes
| Source | Output | Note |
|---|---|---|
| 5 V / 1 A wall charger | 5 W | Recommended |
| Power bank | 5 V | Check it does not auto-sleep |
| PD fast charger | 5/9/12 V | Confirm 5 V negotiation |
Heat and Duty Cycle
LEDs run cool, but the driver and any enclosed cavity around it do not. Run four to eight hours per evening and switch off overnight to keep the driver near ambient. If the housing feels warm after two hours, unplug and check ventilation rather than waiting for a failure, because heat is what shortens the electronics.
Fast Chargers and Batteries
A PD fast charger can work if it negotiates 5 V, but unbranded unregulated adapters risk ripple that stresses the driver. For cordless cells, store at 40–60% charge and top up every three to six months; never store connected inside a sealed carton, because a flat cell left for half a year may refuse to charge.
The short version: material and edition size set the ceiling, finish sets the day-to-day impression, and display decides how much of that you actually see.
