Kinbor Multicolor Rollerball Pen Floating Bay

I bought these pens at 699/- thinking they look pretty and will work flawlessly but to my disappointed, they are not worth their price.The first pack I received, half the pens were not working, so I thought if returning them but their is no option of refund, only replacement.In the second pack only orange and light green are not working smoothly, rest work fine. Although they still don't justify the price. They look average, work fine(not too smooth), the tip is extremely fine(which is a con for me), they were leaking and stained my hands so for the second pack I made sure to clean the pens first with a tissue.
