Chestnut question

I’ve tried to contact chestnut a couple of times asking if their chess pieces are weighted. I’ve gotten no response. Can anyone tell me if the pieces have any added weight to them?

not weighted
I dont mind the total weight of them however

I just weighed 1 piece each from my white set and got the following
This is for the Chessnut Pro
Pawn 8 grams
Rook 16 grams
Knight 20 grams
Bishop 14 grams
Queen 22 grams
King 26 grams
A few things to note, all pieces in the set have a slightly inconsistent weight with the others that share their name

Also, my set is one of the older sets, I believe a few weeks after it they announced they upped the quality of the basic pieces to be a bit heavier. ALSO they released premium pieces which look far better
