❓ Frequently Asked Questions (FAQ)
Will these sea life straw covers fit my 40 oz or 30 oz Stanley Cup straw?
Yes! These straw toppers are specially designed to fit 8mm to 10mm (0.31" – 0.40") diameter straws. They fit standard 10mm straws on Stanley Adventure Quencher (20/30/40 oz), Simple Modern Trek (30/40 oz), Hydro Flask, and standard reusable stainless steel/glass drinking straws.
How does the anti-lost tether ring work?
The bottom flexible silicone loop slides over the straw shaft and stays firmly anchored. When you uncap the character to sip, it hangs right beside the straw so it never falls onto dirty tables, floors, or gets lost.
Are these sea life straw covers dishwasher safe?
Yes! They are top-rack dishwasher safe. You can also quickly rinse them with warm soapy water or boil them for deep sanitization.
