Edit: When you finish using it, screw the cap back on and wrap the area where the cap joins the tube with a piece of electrical tape, the classic electrician's kind. This will keep the glue fresh and moist for years if you do this.
REVIEW: By far the strongest and best Cyanoacrylate glue (super glue)! People just don't know how to use these glues and unfairly give the product a low rating. Unfortunately, I've seen this happen with many products, so be careful, just as you should be when using such glue!
How to use: Clean the surfaces to be glued thoroughly (if you want an even more secure bond, if the surfaces are glossy, sand them a bit before cleaning with some sandpaper to roughen them up). Cut a piece of electrician's electrical tape, about 10 centimeters long, to seal the glue airtight after use! It is also a good idea to wear disposable gloves in case of accidents. Then, carefully open by simply screwing the cap in to pierce the tube. Then, press lightly to get a drop out (depending on the surface to be glued). Remember that you DO NOT need much, because it will overflow and make a mess or you will glue your fingers together, so be careful! Leave the glue standing upright somewhere so the tube doesn't stick and dry out! Immediately, hold the two surfaces firmly without moving or applying too much force for 1 minute. Carefully let go and screw the cap back on so the glue doesn't dry out and seal all around with a long piece of electrician's tape so the glue never dries out! Always keep it upright so the nozzle never closes. (If it does close, cut it with a utility knife for the next use (not too low, just as much as needed). Some people keep it in the fridge, I never put it in the fridge, because if you seal it well with tape and store it upright, it lasts for years. I have used dozens of tubes over 35 years, I haven't seen anything change or the glue not last for at least 2 years from the time it's opened. Store it in a cool place, not near heat or sunlight!!
P.S. If you glue your fingers together, don't panic, because you'll hurt yourself and it will be very painful. Carefully, put your hand under warm water and slowly try to remove it with soap and warm water!! (If a little remains, don't try to remove it all, because you might damage your skin! That's why I recommend disposable gloves.)
