We here at 7th Floor tired of seeing consumers ripped off by unscrupulous e-cig makers. We know you want an oil pen that works, but the Chinese companies use a wide range of materials, and everyone is cutting corners. We can't compete with the factories that pump out these small devices, but there is something that we can do - We at 7th Floor can help by gathering the makers of only the highest quality components, and assembling what we feel to be the best of the best. Rather than see you suffer the indignity of using garbage, we will provide a quality product that we feel comfortable putting our name on, to let the consumer know that this is a product we do support and approve. Every comment or concern brought to us will help in improving these pens, so let your voice be heard!
