InstaFix© 20ml - Quick-drying glue (Cyanoacrylate)

I have been having trouble with mine I clean the end of it when I’m used it I but the lid on then for some reason it gets stuck and I have to use pliers to get it of then after a few times I can’t use it any more and there is still about half left I’ve started buying picture super glue 3 which has the same ingredients with no problems if there is a solution to this love to here it.

first time build. identifying the correct part is sometimes not totally obvious

Awesome kit. Im really enjoy it!!
