Twice a year - on a Sunday in spring and autumn - we invite all Kleinis of the neighbourhood to sell and swap old stuff and homemade items for free at Markthalle Neun. Anything that is not nailed down can be sold. Kleini2Kleini - the flea market for everyone who can count to 100 (except adults).

Have you finished reading your old books? Fancy swapping your football for a basketball? Your roller skates no longer fit? Have you found some great shells on holiday or are you just fed up with your Lego figures? Then come along and join in! There'll be treats for young and old too, of course!

And pssst: this is not a flea market where adults sell children's clothes.
