This is all of the sizes of our super low density squeeze bottles and seven interchangeable tips. The yorker tops are helpful for transfering and storing the paste. Tips are gauges 16,17,18, 19 & 20. The seventh tip is our new 16 gauge flattened oval which is great when the hand needs a break. The shape helps with the pressure but still easy to control of fine lines. All of our tips are 1/2 inch long, scratch and clog resistant!
