The cordsets that we sell are CE certified E27 standard for sale and use in the UK / EU / Rest of world. They are not UL certified E26 standard for North America, so we cannot offer them for sale and delivery to North America.
Our paper shades will work with any pendant cable, so you can source one from wherever you like.
For a similar style you can try Grand Brass. If you are looking for plug-in pendants, the Color Cord Company or Brighttia have a good selection.
If you want to check whether a cordset / pendant works with our shades, please send a link to info@sansho.com and we can confirm whether it will work.
