HOW MANY GRAMS (1 SBD REWARD)

OK, these are the rules:

• I need exact number with one decimal place, example 1.7 grams, 2.8 grams, 5.7 grams...
• First with correct answer is the winner!
• I will announce the winner after the payout of this post.
• You can guess only once!
• 1 SBD reward after payout of this post.

THE NUMBER OF GRAMS IS HIDDEN UNDER THE SPONGE OF A BRA.

SAFE SEX 4 ALL!!!
