You will require 70 to 80 fans per eye to create a full set. That is equivalent to 140 to 160 fans per client. With our 3D lash tray holding 640 fans, you can service around 4 clients. With a 5D volume lash tray containing up to 440 fans, you can serve approximately 3 clients. Pro Tip: With a hybrid set (that's a mix of volume and classic lashes), you can serve 2x the number of clients, which makes the cost per client super affordable.
