kolisong.com Reviews 

Do NOT attempt to do business with this website.
I attempted to purchase a $90 item in November. As of mid March I have not received the item or any communication other than automated emails requesting I review the product. I have reached out several times and gotten no response. I was provided with a tracking number; however, that tracking number populated shipping centers out of order and or with incorrect time stamps. Lastly the refund policy (no refunds until 90 days after the order) appears specifically crafted to prevent disputed charges on credit cards.

Sadly the shop is closed and the owner is disappeared.

Past Review:
Great shop online for Balisong clones.
They have an good deals and prices, with also a delivery tracking service.
If you have something to ask there's a chat on the website or if you have problems you can write them a mail; they usually respond within 24 hours.
No problem with this shop so far: the products are what they describe.
The cost of their products are even lower then the AliExpress shops and they also have a more vast catalog. There's even a point accumulation system with which you can exchange coupons of various types, plus in festivity days the site offers a code for the discount of 8-10% off for every product.
The only things that are negative points are:
-Their products are not always the cheapest even with discounts.
-They don't have the Paypal payment method which is very usefull for most people. (I hope that they will add it).
-This website (like anyone else that ships from china) is the delivery time: I have made a purchase and It was processed in a couple of days but the delivery time was between 15-20; for me it took 15 days.
So if you want to buy a clone this is a good website, but you have to be patient and wait a lot.

Great knives very high quality and worth the price. For beginners and advanced balisong users i highly recommend this company however the only downside is the shipping. Its not the worst but its also not the best but the blades themselves are worth every penny and the customer service is also great.
