Best part is they fit together like a russian nesting doll and take up minimal room in the toolbox, and now come with a shadow tray for display and storage. The stainless insert welded inside the OD of each plug allows for the adjusting of the tightness of fit. Each set is ment to be tuned in for tightness of fit. The back cap is laser cut with 5 orifice for purge outlet. depending on your welding head size these are great for orbital welding short ferrules. These will not fall out or melt like silicone plugs.
