This chess set has a large glass plate with figures which are also made of glass. In others I have often read that it was then but just plastic. The figures are clear indeed are crystal clear, but they look good anyway. On the lower floor of the chess pieces round faces are glued, which help to reduce slippage. However, these are glued partly bad and wrong.
Conclusion: The only shortcoming I find for the price the bad glued subfloor, which can be corrected.
