Our Classic Signature Luxury Silk Extension Trays. These extensions are used and approved of every day in the largest Eyelash Extension Salon in Dallas/Fort Worth. Easy to grip and handle, seamless and jet black. We do not offer anything larger than .15 in Diameter because health of the natural lashes are our top priority. If you are looking for a thicker diameter, we suggest the Flat Lashes. They are light enough and appear thicker than the standard .15mm.
