I'm selling 2 used Hydroflask bottles for a combined cost of $30 for both bottles. Both are in good condition, the lids are great, and the two bottles would retail for $80+tax when new.
Blue bottle: 32 oz wide mouth
Silver bottle: 24 oz wide mouth
You can pick up on campus near Knight Management Center or at Stanford Staff Apartments Colonnade (4750 El Camino Real in Los Altos.)
Cash only, exchanged when we meet. Let me know if you have questions.
