B077RRP9YW & B01N5K59SU:- As I talked to Vikas sir, both products are good. You can import it from Alibaba.com and when you are supposed to import your stock go with sea cargo, not air cargo because air cargo is costly.
B00HH9M8CA:- Medium competition with this product. First of all, check your margin. If you are going to start with this product so go with small stock to check the sales response and please check the quality of the product. You can make some different variations like color, size etc.
