These heavy-duty plastic bags can go the distance! We have several that we've been using nearly 10 years. They are 18" long, and can comfortably hold over 1 lb of paste.
Use these carrot bags to transfer your freshly mixed paste from the bowl into your individual applicators. When done, simply wash with soap and water and stand it upright to allow it to dry fully.
Also excellent for long term storage of fresh paste in your freezer (we still recommend storing in a Ziploc freezer bag for best results).
