Francfranc Stainless Steel Tumbler With Lid, Keeps Drinks Hot or Cold I received this as a gift and have opened it, but it's new and unused. The lid is a twist-off type, making it easy to open. The bottom is made of silicone, which prevents slipping. It has hot and cold insulation, so it can be used all year round. ■ Materials Capacity (approx.): 300ml Body: Stainless steel Heat retention: 75 degrees Celsius or higher (1 hour), 40 degrees Celsius or higher (6 hours) Lid: Polypropylene (heat resistance 110 degrees Celsius) Cold retention: 5 degrees Celsius or lower (1 hour), 11 degrees Celsius or lower (6 hours) Drinking spout gasket: SEBS (heat resistance 110 degrees Celsius) Gasket: Silicone rubber (heat resistance 140 degrees Celsius) Francfranc Tumbler Immediate purchase welcome!
