Looking for yarn in Berlin: Cotton Universal white

Hi everyone,

I’m urgently looking for one or two balls of yarn, specifically:

Cotton Universal by Wolle Rödel in white, 100% cotton, conditioned, 85m/50g

Unfortunately, I ran out of yarn for my crochet project, and right now the only way to order it is online—but I’m just too impatient to wait 9 business days for delivery.

I live in Berlin-Schöneberg (Nollendorfkiez)
I’d be grateful if anyone could help me out. 
Of course, I’d pick up the yarn myself: contactless handoff, with cash payment.

Thank you!
Best regards
Stefan
