Hemp Remedies has been producing their Releaf CBD Dabsfor quite a while now and many people swear by it. Its available in 1 gram (1000mg) jars and can be purchased in either 24% (240mg CBD) or 41% (410mg) strength.

This is the only brand of CBD Dabs that I've found to be a true dab or wax. Most are just a thick version of the brand's oils. Anyway, hope this helps!
