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.
This are highly absorbent, so when you work on surfaces that keep getting wet and you need to keep them dry, don't blink an eye and get these. I use these in kitchen, bathrooms, wherever possible. Easy to clean these, just soak all microfibercloth together in a mild detergent line genteel, then wash them together in the gentle cycle of your washing machine. avoid putting other regular clothes with microfibercloths, as microfiber is magnets for dust and lint.
Excellent quality! I was spending more than twice the money for similar quality microfiber cleaning cloth. I am extremely hapoy with this AmazonBasics product purchase, and henceforth I will buy these for my needs. Keep up the good work Amazon.
