You will receive this silicone mold from us and can pour yourself a plaster stabilizer with the BioFlow , another plaster cast.
Please take a rail foil and wax your stumps tightly, enclose the whole thing with our plaster mold and then fill the whole thing with duplicate silicone and after 30 to 40 minutes you can then unmold the stumps.
Another advantage is that you can then archive the form and use it over and over again.
