Cartridge Use: Our cartridges are compatible with 510 batteries. The Delta 8 we source is very stable due to the high quality and potency. In order to ensure smooth hits, uphold the life of the cartridge, and allow for easier pulls, always use the pre-heat setting a couple times to warm up the distillate before taking a hit. The coil must be fully saturated to prevent it from burning which can alter the taste of the oil or even ruin the coil. Keep cartridges out of direct sunlight as this may cause leaking and store cartridges up right when not in use.
