Description: These blue cases disappeared somewhere along my bike ride between Potrero Hill and Noe Valley, as I was riding down De Haro, 17th, Valencia, 22nd, Church, and 23rd. They were in the pannier of my cargo bike, which somehow opened. If you saw them, please let me know, even if you don’t currently have them. Just knowing where they may have ended up would be helpful. They are prototype investigational medical devices and should not be used without medical supervision. Reward offered.
