I Found These At My Grandma’s House And Have No Idea What They Are

I can write a detailed breakdown, but right now I don’t actually know what “these” are—there’s no photo or description attached.

To give you a proper identification (and a 1000-word level explanation like you asked), I need at least one of the following:

A clear photo of the items
Or a description like:
Size (tiny / palm-sized / large)
Material (metal, wood, glass, plastic, cloth)
Shape (round, flat, tools, coins, jewelry-like, etc.)
Any markings, numbers, or writing
Where they were found (box, kitchen, trunk, storage room)
Why this matters
Old items at grandparents’ houses can be from completely different categories, for example:

Antiques or heirlooms (old coins, jewelry, utensils, tools)
Household utility items (vintage kitchen tools, sewing kits, sewing machine parts)
Religious or cultural objects (prayer beads, charms, incense holders)
Medical or grooming tools (old razors, syringes, massage tools)
Electronics or mechanical parts (radio components, batteries, adapters)
Collectibles or toys (marbles, stamps, trading items)
Each of these requires totally different interpretation, and guessing without seeing them would likely be wrong.
