I tried this on binding and love i.. Someone one here had a metal one. Went looking for one. Someone said hobby lobby in the paint area. Was not there. Tried the glue area not there. I did find in the art dept. Small plastic bottles with very small tips. $2.99 plus my coupon. If I do not like it I am not out a lot of money. Would really like the metal one because it screws right on the bottle. Any ideas where and how much? Thanks!
