Working in the nail industry for over 20 years, it is important to use products that work and do as advertised to be efficient. By far this is the best adhesive for nail enhancements I have used in a very long time.
There had been others in the past that were terrific, but only guessing due to cutting costs to make more profits these previous terrific glues are no longer as good and efficient to use in my industry(big indication was a 4 year ago opened tube in the freezer was found with lid on. Still very fluid and and in good working order. Newer tubes, same brand bought in the last 6 months went hard- solid hard. Once opened they never lasted more than a day. No longer fluid and fast drying but thick and slow drying or not drying at all. I will not name this brand. It is still found in popular salon supply stores in Australia).
I am happy to say I have finally found one that is perfect. It really is fast drying, every time. it really is strong and long lasting and does not help to create fungal under the nail. Also, if a tube is opened today and not used for 2 weeks(had to test the longevity of an opened tube) and not refrigerated, its performance and viscosity is still as perfect as the day it was opened providing the lid was left on(did not try it with lid off).
Please don't just take my word for it. There is an option to buy one to try first. I do hope you love this glue as much as I do.
