Difference between M101, M111, HD111
The M101 is a clear thin SKIN base (in 8 mils thickness). It comes in an 8"x10" size and can be cut down to any size. The hair density on the unit is 110% at the front while the rest is 100%.
The M111 is a clear thin SKIN base (in 3 mils thickness). The hair strands on this unit is V-looped, meaning that each strand of hair is inserted into the base and the other end of the strand is inserted out. V-looped units typically are more fragile compared to the other hair pieces we offer because the other units are usually KNOTTED at the base. V-looped strands can easily come out if you run your hands/fingers through the unit while wet, or if your brush your hair kind of rough - it'll shed easily. The M111 comes in a 8"x10" size and can also be cut down to any size. The hair density on the unit is 80% light density with 15% extra density on the 1" rim.
The HD111 is also a clear thin skin base (in 4 mils thickness). This unit is ALSO made using the V-looped method. It comes in an 8"x10" size and can be cut down to any size. The hair density on this unit is 95% (HD means higher density, thus giving the name HD111 because the M111 and HD111 are essentially the same unit but with a bit more density and 1 mils thickness difference on the HD111)
