I am happy to purchase products from sign-in-china. Product quality is very good and shipping is very fast. The packaging is intact. Most of the ink I purchased has been used. I am very satisfied with this product purchase. I always buy ink here. Thank you for your help.

Bought some ink cartridges from sign in china, performed just as good as the original ones. And it’s much much cheaper!

I’m using this brand of ink on my printer for a test, the color is good!

Will came back to buy again ,and except the mimaki Ink Cartridges, other parts also used well till now

One of my friend introduced this shop to me,i bought several pieces of US Stock Calca Compatible 440ml Roland ECO-Sol Max In.I am so happy for their good package and after testing,i decide to give them five star positive feedback.s

Very good ink! I never get problem with this ink, never clog the printheads!

I’m reluctant to recommend you this ink because it’s way too good, as good as the original Roland inks, while the price is so much cheaper.

duringpast,I regularly purchased much printer spare parts ,nowadays I started to try to push ink, to my client,what did not expect,,it work good ,the price is competitive ,in future ,I will continue buying ink from you guys .

I have bought products in your company many times. I’m very satisfied with both the product quality and your service. I’ll continue to buy next time and hope we can cooperate happily.
