These spreaders have been used in the general craft market for years, where they are used to apply glue to felts, paper, card board, etc, or for working with thick paints to create special patterns. The tip is flexible and can be used with various amounts of pressure. Glue won't stick to the polypropylene plastic and dried glue just chips off . The Glue Spreader kit comes in a convenient 6 pack of multi colored spreaders / applicators.
