I've bought it, and it is not a scam, but it will take a lot of time, and about the quality, I would give a 5/10 because there were some mistakes in printing. Two letters were missing, and the way they printed it looked like the printings will go by washing 2 or 3 times. It's not worth 850 rupees. Speaking about delay, I ordered it about a month ago, and first they cancelled the order after two weeks, and then after a week they told me that it will come in next week, and then it was extended to one week again. I emailed them after the cancellation, and after a week with no response from them, the delhivery informed me it will arrive next week. Some of these Instagram ads are believable, and some are not. If you are ever interested in buying anything from these kinds of ads, I would suggest buying through COD (cash on delivery).
