Notch Jar

An hour in the morning is worth two in the evening. Breakfast is the most important of a day. Toast with jam is the most convenient and rapid way for commuters.
But it is troublesome after using the knife to spread the jam. This is why we have come out a design for this product to avoid this inconvenience for commuters.We have design a gap in side of the jam jar, which allowed knife to scrape off the jam.Notch Jar can avoid the waste of jam and also can save times for commuters.
