I recently bought the 48 pack of alcohol brush markers from ohuhu. It was of great dismay when I realized two of my markers were dried either upon arrival or after a few uses. I contacted customer service and was satisfied when they said they were going to send two new markers in order to replace the dried ones in my collection. The customer service was great, I had no complications or complainants. The product is also amazing. I am just getting into using alcohol markers and ohuhu markers are definitely a good place to start. There is a variety of colors that are easy to blend. The brush tip is firm and easy to work with. I overall recommend this product to people who don’t want to break the bank to purchase good alcohol markers. Amazing customer service and an awesome product.
