History of SK Concepts



SK Concepts was founded in 2010 with a clear vision: to become a leader in custom packaging solutions for the tobacco and herb industries. Starting as a printing company, we specialized in folding cartons, turned edge boxes, and mylar packaging. Over time, we expanded into assembly and introduced customized solutions for a range of markets, including tobacco, herb, chocolate, and premium FMCG.

In 2012, we established our first Roll Your Own (RYO) division, which led to the creation of StarRolls.com for manufacturing rolling paper booklets. This division marked the beginning of our deep involvement in the pre-roll industry. The same paper bobbins and crutch tips used in StarRolls were adapted to create the products used by RollProsSupplies.com. While StarRolls focuses on producing rolling paper in a flat format, RollProsSupplies specializes in pre-roll joints specifically designed for the Blackbird machine, providing a seamless transition from flat paper to pre-roll joints. The key difference is that pre-roll cones are different from pre-roll joints. The Blackbird machine produces pre-roll joints, which are cylindrical, mimicking the hand-rolled style, while pre-roll cones are typically cone-shaped.

Through our commitment to quality, customer service, and flexibility, SK Concepts has become a one-stop shop for brands, wholesalers, and retailers who need custom solutions for pre-roll joint production and packaging. With over 250 people in our manufacturing team, we’re now recognized globally, particularly in North America, Europe, and Canada.
