na-adjective, noun which may take the genitive case particle 'no'

空からっぽ
空っぽ is a more neutral and common word for 'empty', while すっからかん is more emphatic and colloquial, often implying a complete lack.
すってんてん
すってんてん also means 'penniless' or 'broke', but is slightly more playful and less common than すっからかん.

The word is likely a sound-symbolic (mimetic) formation emphasizing emptiness, with the prefix すっ- adding intensity. The exact origin is uncertain.
