Absolutely no chance with smooth soft plastics (ok it's the hardest material but it says it's for plastics and it costs like it's the top) like transparent fabrics even after 48 hours. It stretches very easily, literally like wax, without sticking at all in tests that even the surfaces were first sanded well with sandpaper for better adhesion of the glue. For its price especially and such a small quantity, I did not expect such a ridiculous performance. Worse than the ones I get at the kiosk.

In contrast, the Bostik Gel Soft Plastics (at almost half the price, although success counts not the 2 euros) holds incredibly strong even on completely smooth surfaces (without sanding with sandpaper).

My second test with hard plastics was absolutely successful so I came back to add a star, but not more because with less money you can get better glues than this and in 2.5 times greater quantity.
