Appropriate
Avoid when
You can say "可以看一下吗?" (kěyǐ kàn yíxià ma?). It is a polite way to ask to see something in a shop.
It is pronounced "kěyǐ kàn yíxià ma?". Pay attention to the tone changes: 可以 (kěyǐ) has a third tone on both syllables, but in natural speech, the first 可 (kě) often becomes a half-third tone.
Use it in a shop when you want to inspect a product before buying. It is polite and common in retail contexts.
