did a search for "Watteschnur" and seen prices as low as €11,66 (inclusive)
whatever lavabis is?

or from the bay €9,00

If I didn't still have 80+ sheets of muji I might consider buying it - pity I don't know someone about to buy cotton, I'd happily go halves or even 1/16th's :) 1kg is way more than I need..
