Mercedez's multi blue wand or the Lucid Heart. Stay away from the Rainbow nubby if this is your first glass piece. Or if your interested in texture for your first glass piece go with one like Pink Double G
because you'll get to try two textures in one toy. Nubs are painful for some and some people can't feel them at all. You should know if you like them prior to purchasing a completely nubbed glass toy. Glass is also a material that is something you need to get use to.
