These are 5 pairs of upper and lower perforated trays of extra small, small, medium, large and extra-large size.
Trays have soft edges with an undercut made with a welded wire for the better retention of alginate.
Its highly polished surface make it easy to remove the dry impression material.
It is normal to get foggy when put inside the mouth. Its foggy-ness does not affect its retention to hold the impression material because retention is mainly derived from the perforated surface and margins with the undercut.
Its fogginess can be avoided in winter by heating it a little bit with a hair dryer or other hot air sources.
