Buy AK-47 – THC Syringe UK Online. Our AK-47 SYRINGE is a 2 ml graduated glass, containing the highest quality tetrahydrocannabinol on the market. It’s 100% hemp-derived and federally legal. AK-47 SYRINGE is a highly viscous, clear to medium amber, translucent oil that will not crystallize. It is so viscous that at low temperatures it behaves almost like a solid. Because of this, you will not be able to push the oil out of the syringe without first heating it or you may end up breaking the glass syringe or the plastic plunger.
