Karaku Reviews 

I mirror the other 1* reviews. This business pretends to be from the USA - it isn't - it's from China.
This is a really dreadful company to deal with.
Their products are cheap, nasty Chinese tat which do not fit.
They have a no refund policy and if you send the gear back, they actually ask you to break the law and lie about the value "make sure you do not value the goods above 2GBP" AND they take 6% fee from your refund.
I absolutely cannot stand this company, it's everything corrupt you hear about some Chinese businesses.
AVOID

The lowest quality imaginable. It is like wearing a sack. I had thought at the price it was a high quality Japanese product, but was disappointed to find it was in fact Chinese. A huge disappointment. Don’t be deceived!

Ordered a size Large and received an incorrect item. I paid return shipping to exchange it and was still not provided a satisfactory resolution. Customer service insisted I pay additional fees to receive the correct item or accept store credit. A refund was refused unless I returned the item again at my expense with added handling fees. Poor handling of a straightforward fulfillment issue.

The shirts look great on line. Due to some of the reviews I went a size up. Delivery took over two weeks. The shirts were way over sized. Massive! I returned them for an exchange. I had to pay over £28 for the return plus another £12.50 for the new shirts to be sent back. Another very long wait. New shirts arrived. Still way too big and this was the size I’d normally go for. Despite the ridiculous return cost I enquired about either returning for a smaller size or a refund. I received a response saying that they only offer one exchange or refund and as I had already had one exchange they were unable to help. This is not clear on their website.
The shirts are not even very nice. They are cheaply made and shapeless. A total waste of money. In short I suggest only buying if you know your exact size in these particular shirts and if you do have to return an item get a refund not an exchange.
