I like these tips. They fit on the end of any Testers Cement very nicely. I wish they made a non-disposable version, but if you stick a pin through the end of the tip, you can use it again. They concentrate the glue very well. Worth the purchase price.

This is a must have for gluing small detail pieces together.

no problems, just stick a pin in the top or thumbtack so it does not dry closed when done using.
