I've used other tips and they can leak, but not these. Helped limit amount of glue in the precise spots I needed.

I'm so happy I found these on Hobbylinc's website they pinpoint the cement where you want it in hard to reach areas of your model I get about 4 uses out of one glue tip excellent item.

I bought these tips for the brand of ca glue that I have been using for the past couple of years, but found that they didn't fit the container too well. so I started buying the bsi glue that you sell, and I couldn't be happier! The tips rarely clog, and when they do, just take an exacto knife and barely nip the end. Voila, good to go! Thanks, Hobbylinc, for another great and handy product! Sincerely, Rick
