One of the fastest-acting, most accurately dosed cannabis products available. Mary’s patented gel pens have been reported to pair well with other Mary’s products, but can also be used on their own to create custom cannabinoid ratios. The gel pens take between 5 to 15 minutes to onset and have a duration of 2 to 6 hours. Great for rapid relief as well as an easy, on-the-go option! Approximately (50) 4 mg per metered pump.
