Are these earrings real gold or silver?

No. They are gold-plated fashion metal, not solid gold or sterling silver. Expect the plating to fade with wear, especially if you wear them often.

The listing does not give an exact length, but the elongated cross design is a long drop style. Check the product photos against a known object before buying if length matters to you.

Are they heavy or uncomfortable?

They are light metal, so the main issue is swing and snagging rather than weight. Long drops can catch on hair and collars.

Can I wear them if I have sensitive ears?

There is no hypoallergenic claim. If your ears react to nickel or plated metals, these are a risk and you should look for surgical steel or sterling silver instead.

What comes in one order?

One order of one unit is one pair. Choosing two units gives two pairs, and so on, so buy the number of pairs you actually want.

Do they suit men as well as women?

The listing describes them as women's earrings, but the cross drop style is unisex in practice. Fit and comfort depend on the earring post, which is not specified.
