Sluban are a Lego clone company, originating from China, and trading under the name of Oxford in Korea, I’m not entirely sure as the packaging and photos seem the same.
I’ve found various places including Wilkinsons (thanks Jasbrick) and Ebay that sell Sluban. It seems that Oxford, produce more products than Sluban. Additionally I found a Dutch website that seems associated with Sluban.
The Sluban bricks are virtually identical to Lego bricks and whilst the suffer from being slightly poorer quality anf finish, they seem to fit with Lego bricks fairly well. The Minifigs however are pretty useless, the minifigs are made similar to Lego minifigs with the same joint movements as a Lego minifig, however the significant difference in the sluban minifigs is the Legs, these are connected to the body differently and the Legs are more shaped, in actual facts this actually works against the Sluban minifig.
The one key feature about sluban that is brilliant is the minifig helmet (in this case), and the chest piece which Jasbrick commonly uses, these minifig helmets fit perfectly on a Lego minifig and are Idea for any custom minifig work you might choose to do.
When you consider that the Sluban Box I bought cost me less than £1.50 when I bought it in a market in south east asia, and i got two minifig helmets from it, that’s about £0.75 per helmet which isn’t too bad, and as for the bricks, I’ll probably still use them.
