It's an AmazonBasics "pack of 3 ultra thick microfiber cleaning cloth", made of 90% polyester & 10% polyamide.
It's product name is B00EVY2SKG, "Made in China" and imported by Cloudtail, Delhi.
Each piece measures 60x40cm in size (quite big and great for car cleaning) and the set weights a total of 250gms.
So it's, by calculation, 350 GSM cloth.
I didn't buy it at any lightning offers or so and got the pack at Rs.449, which is just ok price-wise.
Although soft to touch, the "polyster" feel is not welcoming for dry hands, but since it's purpose is not a handkerchief, no points lost there.
However, it lost one point for advertising that it soaks 8 times it's weight of water. It CANNOT soak more than 5 times it's weight. For numbers, in bone-dry condition, it soaked 400gm/270ml of tap water.
Further, in straight-out continuous usage ie. a single cleaning session, I might be able to drain out about 4 times it's weight of water before again sucking in another 4 times it's weight, in continuous turns.
Need to check in other claims that dirt clings onto it while cleaning. More updates in due time.
