Compare alloy, finish and weight
Identify what the listing says about the finished product.
Read the alloy line
Stainless steel and aluminum alloy are different materials. Check whether the listing specifies an alloy or gives a general name. Treat claims about finish or plating separately from the core material.
Find the actual weight
Overall size alone does not give weight. A hollow product and a solid product can feel different even when they have similar dimensions. Ask for weight in grams or ounces if the listing gives no figure.
