Hello,

Unfortunately I have no info about the brand or
catalog number, I bought it off the shelf by piece (I
mean not a full pack) so I have no details. Next time
I will go at that store I will ask for a full pack and
look for the brand/part number and share the info.
I just asked for chalk coated paper.

Best regards,

Mihai
