When I received my package of these 2 fine tip glue applicators, I had my misgivings. One of the metal toppers was tilted and nearly off, which led to concerns as to what would happen when trying to squeeze fairly thick glue through the tiny tip opening. I tried it out the first time yesterday using tacky glue on a delicate die cut, and to my delight, the top did NOT go flying off as Iíd feared and it worked great. Itís the first time Iíve been able to put delicate die cut words on the front of a card and not have ďnearly but not quite invisibleĒ traces of glue around it. I do wish those metal caps screwed on, though, rather than just being pressed down on the bottle tip. Thank you - very happy with them thus far.
