Bear Rootz Inc. is always looking for the next top products and we are proud to present our Wholesale Hybrid category. Each pen that is available in this category is very unique in that it has two or more functions. Not only can they be used with 510 threaded cartridges, they can also be used for dabbing as well. There are not many of these Hybrid devices out on the market and we will continue to grow our offerings as technology advances. These Hybrid pens are available in bulk.
