There is nothing worse than having a bottle filled with a liquid or eggs break on the way home from grocery shopping. Well there is but lets not think about what that might be :). These quilted bags are made to help with that problem. Large bag has four holders to keep 2-liter bottles separated and lots of room for groceries. Medium bag has four separations each holding a 1-liter bottle and groceries. Small bag holds six wine bottles. Very small bag holds one wine bottle.
