These are 1/2 ounce squeeze bottles with a special metal tip that screws onto the top. The tip and bottle come as a set. Extra bottles can be purchased separately. The metal tips gives a very fine line. Comes in three sizes #5, #7, #9 (thin to thick). Useful for applying gutta, water based resists and medium to thick consistency paints or thickened dyes in a fine line.
Note: To fill the bottle, just pop out the plastic tip and then replace before use. (A funnel is helpful for filling!)
