Glas e Liquid is a US brand of rich deep flavoursome juices for vaping that features the line Glas Basix.
Glas Basix E liquid is synonymous with sweetened dessert and cream style VG liquids. These are great for high powered vaporisers and will meet most needs for making thick clouds.
Due to their sweetened nature, they can be a little more heavy going on your coil, but if you want quality, Glas E-liquid gives you that. You may also find them by searching Glas Basix.
