Q1: My cup doesn’t fit. Why?

A: Measure your cup outer rim-it must be 3.46–3.62 in / 8.8–9.2 cm. Smaller rims won’t seal tight.

Q2: Fit Starbucks mugs?

A: Only if your mug rim is 8.8–9.2 cm. Special rims need other sizes.

Q3: Why no tight seal?

A: Best for straight smooth rims. Textured/angled/small rims affect sealing.

Q4: Is slight silicone smell normal?

A: Yes. Air out 1–2 days or wash—smell will disappear.
