We're all been there, pushing our glasses up our nose only to do it again as soon as they fall back down. There's a better way. Nerdwax is an all-natural beeswax blend specially formulated to keep your glasses in place. The ingredients are cosmetic grade, which just means that it's good for your skin...not just for keeping your glasses in place. Application times can vary from 1-2 hours to a full day depending on how much is applied and the activity being enjoyed! A single tube of Nerdwax is estimated to last 6 to 8 months.
