3M Micro pore tape. Bulk buy! Sold in a 4 roll bundle. Save $2 by buying this way. This is an alternative to use for taping down the lower lashes. I find this uncomfortable for clients & would prefer to use pads. It is the cheaper alternative though. We also use this tape for lifting lids and sideways taping.
It is very handy for taping up lids to get to those tricky lashes, so a must have for this purpose. 3M tape is a staple product for all lash artists.
