Ultra Thin
TrollFoil is only 8 µm thin. This thin foil helps reduce the pseudo contacts that can occur with thicker materials. TrollFoil provides clear, pinpoint markings without smearing.
TrollFoil records contacts on both arches at once, supporting clear assessment of corresponding contact points.
This allows one-handed placement and keeps the foil flat and tensioned during use. No Miller forceps needed.
Double-Sided Advantage
One-Handed Placement
Reliable Marks - Wet or Dry
