"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 !
