The residence of the Hagaon Rabbi Chaim Kanievsky in Bnei Brak is filled with thousands of people seeking advice and brachos. Being that in addition to receiving the constant flow of people he receives thousands of letters with questions in torah and halachah. The Rav takes the time to answer each letter personally, especially on Tuesday, when there is no public reception.
Therefore many people just opted to write Kvitlach (notes) mentioning their requests for Reb Chaim’s Review.
Now, in order to make it even easier for the people who deposit their written requests to the affixed mailbox, they installed a stand with pages and pens in the home, so that the people can write the names and put them directly in to the mailbox.
The Gabaaim committed that all the kvitlach will be presented to Reb Chaim and he will review each and everyone, and provide his brachos and advice subsequently.
