Up for sale is a LIGHTLY USED Hori Wired Internet LAN Adapter for Nintendo Switch.  This will make your first gen Switch be able to have a wired connection rather than only WiFi.  I bought this and used it for a couple months before I decided to sell off my Switch, so my loss is your gain.  This will ship via USPS Priority Mail in a box.  If you have any questions, please do not hesitate to ask and thanks for looking!
