Basically, the board of two bonded layers of bamboo. Looks a bit "cheap", but so far came off nothing and boards are currently plan on the table.
For the price that's more than OK!
One more thing:
Love people who have a mania for cleanliness. These are wooden boards and on no account in a dishwasher (like sharp knives have nothing to do there!)!
The boards after use simply wipe with a damp cloth - done. Be careful during heavy soiling that the wood not long stays wet.
Actually, I do not think much of such phrases, but I'm not about to write: Wood is a natural product and is working ...
