This is a set of three items for sale: 1. Elecom Trackball Mouse (M-DT1DRBK) 2. Logitech Webcam (C270) 3. Logitech Headset (H111R) These items were purchased and used before the COVID-19 pandemic, starting around 2018, and have been stored away since then. I connected them to a PC to check their basic functionality before listing them. Please understand that these are used items and purchase accordingly. The headset's ear pads are deteriorated, so you may want to replace them or purchase with the understanding of their condition (consider them a bonus). Please ask if you have any questions. Thank you for your consideration.
