Every board has a tag in mirror writing. It is situated under the board and can be read by the owner by simply putting a small mirror on the soil in front of the tag.
This tag gives you a code that will enable us to give you information on the origin of the wood, the date of production, the GBF, the reseller, the previous owner and other specifications so that both you and us can be reassured on the safety of the product.
Remember, only a board from Mikel Tube® will fully respond to your expectations. Thats why MWID (or Mirror Writing Identification) was set up.
