The product description "The package includes 2 tubes of this powerful two-component glue that sticks everything" is misleading, you actually buy one bottle, it's just an oil-based glue, oil-based glues are quite different from cyanoacrylate, they are different and thicker, e.g. if you drop some on marble and let it dry, you can easily remove it with a scraper, but it leaves a slight stain like oil, it bonds many materials strongly with a thicker layer, anyway it's impossible to use very little, the bonding lasts for a while, less than a minute, but you have to leave it overnight to fully set, there is some shifting in the pieces, only on one type of ceramic did it not move, of course it is contraindicated for glass and sensitive materials, glasses and any refined work, it thickens as less product remains, you never cut the tip as you use it, the cap has an indentation, you clean it with work scissors in a circular motion, it is particularly durable plastic, among the advantages are the economy due to quantity and price but you can't do everything with this glue. This particular one is good as long as you follow the above, but in the heat it clogs inside, I cleaned it but then the nozzle stretched and then it runs a lot, I put a cap with a pin from another glue, the long bottle is unstable and it takes a long time to come down, when three quarters or less remain, also when it came out it had two bottles with a white and a green cap, they are not the same, the white one has a closed nozzle and needs to be cut, the green one doesn't and is stronger, anyway glues with a white cap are always the weakest, now they only show the white one, I don't know if I will buy it again, unfortunately here they only bring two oil-based ones
