"Streichholzschächtelchen" is the belittlement of matchbox. Matchbox in German means "Streichholzschachtel" :) I am not a native English speaker, but I think ''Streichholzschächtelchen'' in English just means ''little matchbox''
Streichholzschachtel = matchbox
Streichholzschächtelchen = little matchbox
Correct me if I am wrong !
