Dye i3 foam

[Russ. M]

Hi guys
In the process of rebuilding/cleaning an old pair of i3 for my daughter to use. Unfortunately after a short soak in warm water to clean out the gunk from the lens frame the foams have stripped off.

Are these fixable? Can they be glued back in place or is it gonna be a new lens frame? If its fixable anyone able to recommend which glue to use

Thanks in advance

Contact cement works, apply to both, let dry to the touch then press together. Alternatively I have a set of i3s I'm not going to be using :-/
