You gaze down with interest at the still unopened package, deft fingers playing over its surface, careful not to snag a talon in its wrapping. It's not a small bundle by any means; then again, with your uncle's vaunted stature, that doesn't mean a whole lot. He remains one of the few dragons to retain a trace of the impressive size and bearing that will ensure the eternal status of draconity in the most cherished tales and legends, human and otherwise... And so what might seem a large accessory or object to another would be for him only just this side of too minuscule to be used.
...But enough about him. You have a present to savor.
It would be easy enough to tear free the wrappings and feast your eyes on the contents... but why be impatient? Leave the breakneck hastiness to the humans. Turning, you sit down in the large, impressive, and exquisitely comfortable chair just to the side of your dresser, well-worn from years of bearing your own similarly impressive frame in times of thought or contemplation. Much like the rest of your possessions and furnishings, it has an elegance, a style, more and more difficult to come across...
well, outside of a dragon's lair, at least. Even among beings so long-lived, some things will never change, and for you that includes a deep commitment to luxury and comfort in the interior of your home... and dignity, as well. On those few occasions when you must suffer human company to enter on business of whatever fashion, they are always suitably impressed and humbled. The dragons of yore may have rested upon heaps and piles of coinage, but with a more human-like body- well, discounting your tremendous advantage of size, of course- comes an ability to appreciate finer and admittedly more pleasant accomodations.
Whether they ever make it back into the world outside, after being so impressed and humbled? That's another matter entirely.
Grinning, a light and rumbling purr escaping your handsomely-scaled throat, you wonder, at your own size, whether you truly even need such a device as your uncle possessed. Certainly the possibilities of what you could do with such an ability are endless... but at the same time, there are others among your kin not so blessed with size as yourself who could probably use it much, much more.
That being considered... Probably not the secret of his shrinking ability, tantalizing as the possibility is. But what, then? Having savored the mystery for long enough, you slide your fingers into the wrapping's edge and start to work it loose...
