The most useful accessory-storage system tells you what each part belongs to without requiring you to test it on a figure. Keep the exact product name and version with every group of spare pieces. Similar-looking hands or supports are not necessarily interchangeable.
Record the original contents
Photograph all parts beside the manual when you first check the figure. Mark which ones are fitted and which are stored. Keep a copy of the original contents list so you can distinguish a missing component from an optional one.
Label storage by product, not just character. Two releases of the same character may use different connections. Add a photograph or inventory number if their names are easy to confuse.
Separate surfaces and fragile shapes
Use the original fitted packaging when it remains suitable. Keep thin projections from carrying the weight of other parts, and avoid rubbing painted faces together. Follow product-specific storage guidance for cloth, transparent parts and unusual finishes.
Do not assume any plastic bag, foam or adhesive label is suitable for direct long-term contact with paint. Put identifying labels on the outside of the container and keep parts accessible without pulling on delicate areas.
Update the record when you change a pose
Before swapping accessories, prepare a clear work area and the correct container. Return the removed pieces immediately, then update your photograph if the display configuration changed. This prevents a temporary placement from becoming a mystery drawer.
For purchases from Super Saiyan Sphere, save the product page and assembly information alongside the storage record. If a piece is unidentified, resolve its origin before fitting it. Organization should reduce handling, not create more trial-and-error assembly.
