Super Seal is one of the best adhesives on the market. It dries really fast and does not leave clumps of adhesive on the lashes. The consistency is thin and translucent, leaving the lashes as if they grew out naturally from the clients lids. The bonding time is up to 6 weeks. This duo is great because you have options of using clear & black. This is MUST PURCHASE product. Great for eyelash and eyebrow extensions.
