It’s really good experience at sign-in-global.com. The ink works well and I will get more soon.

Great speed of delivery and quality of product. I love everyone who made this,hope your business gonna be better and better

The communication was pleasant and the quality of the customized products was good, far beyond my expectations

Top-notch quality at a very reasonable price. The customer support was also very responsive and helpful.

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.

It delivered earlier. I’ve used them and printing is so good. This calca ink fits all model and type for Roland. The point is that it is affordable. I think I will buy more. And the service also great. Many thanks

Very good ink, nice colour and dry fast.

I bought them as a back up and found out they are great. 1/2 of OEM carts and just as good it will pay for its self times 2 over.

Bulk ink is the way to go. Lasts longer and better quality

Don't Pay the high prices of OEM this is better and Less expensive

wow i both 2 of them and now i buy one more make sure you follow their instruction

i use on my roland but you need to buy the chip which telles the ink is full you can buy the chip here too

Good colors, same as origional
