Sapphire Bundle

Our deep, metallic Sapphire blue is one of our most popular hues! We put this battery pair together so you can try out the OG Slim Twist Pen and the updated Twist Slim Pen 2.0, both in your favorite blue. Jewel tones are so in!

Don’t get it twisted, you don’t have to use both of these batteries for 510 cartridges! We’ve got all sorts of different attachments that let you transform your new batts into something new. Try out a Hot Knife, a Glass Globe, or a ConNectar; there are tons of options! Or, you can keep it simple and use one pen at a time, keeping the other charged as a backup in case your go-to dies.
