Dear all, I need some help. I have four specimens of Laevicardium mortoni
in my collection. The valves can come seperate from each other, and this
becomes
annoying when i'm trying to rearrange. I need a method to hold them
together, but I don't
want to glue, cause the interior is just as important as the exterior. I
also need a method
to hold together some Anamalocardia auberiana specimens.

Thanks,
James
