MODE Silk Base Lace Wigs are one of the most realistic lace wig caps on the market today. A Silk Base Wig also known as a Silk Top Wig are when the knots are hidden by a layer of lace, and silk fabric on the top front of the cap. When the hair is knotted, the knots are below the silk concealed between these layers, the hair is then injected through the silk material making the knots 100% invisible, giving the illusion that the hair is actually growing out of your scalp. With these wigs, there is no need to hide the grids of the lace and we also bleach the knots around the silk base for a flawless blend from lace to silk .
