Hello, bird's nests are the nests of swiftlets, and the size of each one is different.

Generally, the weight of feathered bird's nest is about 6-10g. After picking, processing and air-drying, the average large bird's nest is about 8g, which is already a very large bird's nest. Small cup of 4-6g.

If the bird's nest you buy is about 10g per cup, you should be careful. It is better to look at the picture above.

Distinguish the authenticity of the bird's nest:

Look at the appearance: Check whether the texture of the bird's nest is clear. If the bird's nest is very smooth, it may be glued (to make money for the weight)

This is a photo of our bird's nest taken with a mobile phone. The effect is not very good, but you can see the appearance and texture very clearly.

Let me show you a glued bird's nest below

Did you see the bird's nest in the picture above? It will weigh more after it is glued.

In addition, you can buy a few more to compare. If you choose a certain product that comes with free shipping insurance, you can return it.
