The picture makes the tin look bigger than it is, I should have looked at the product description more closely. Its only 16cm diameter and 6cm high, which is way too small really, couple of tablespoons from one of the containers and a refill is required. One of the containers is not finished well and has a very sharp abrasive edge.
Once you screw the small knob to the inner lid the outer lid will no longer push down to create an airtight seal, so pointless really!
Overall I personally am not impressed and will have to buy a better one.
Also, it was delivered quickly but not well packaged only protected by a thin bubble-wrap envelope, so it was dented when it arrived.
