Frequently asked questions

Will these straws fit every 40 oz tumbler?
They’re designed to fit Stanley Quencher H1.0/H2.0, Stanley 40 oz tumblers with handle, and Simple Modern 40 oz tumblers. Because lid openings vary between brands, confirm your lid opening size — the 0.75" diameter is a common size for standard drink flow.
Are the silicone tips removable?
Yes — the black silicone tips are removable for cleaning or replacement.
Can I use these for hot beverages?
Yes. The 18/8 stainless core tolerates hot liquids; the silicone tip helps protect lips from high temperatures.
How long will these last?
With proper care, stainless steel straws typically last for years. The main wear points are silicone tips; replace tips if they tear or show heavy wear.
