Our strain-specific oils and easy-to-use pens are designed for consistency and clarity—so you can focus on feeling good, not figuring things out. We’re here for the curious, the casual, and the connoisseurs alike.

For our retail partners, we offer over 40 strain options across three tiered product lines: Daily Strains, Signature Strains, and Elite Strains—each crafted to meet consumers where they are in their cannabis journey. All products are powered by industry-leading C-Cell hardware in both 510-thread and all-in-one formats. With 13 awards for oil quality, O.pen delivers a premium experience that outperforms at retail, drives repeat purchases, and stands out in a crowded market.

If you're cartridge stops working, is leaking or you just don't like the taste, we want to work with you to find something you love. Please take it to the O.pen retailer you purchased it at or contact us to facilitate an exchange.
