This is KAPLA. The following is a description of the product from the manufacturer's website: Art Book Color: Red (Intermediate) Material: 100% Natural Wood Box Size: Width 25cm x Depth 25cm x Height 35cm (Plank Size: 0.8 x 2.4 x 12cm) Weight: Approximately 6.5kg Age Recommendation: 3 years old and up Includes: 280 white wood KAPLA pieces (Accessories: Art book, instruction booklet, wooden box) I have used this product less than 10 times since purchasing it, and it has mostly been stored in a storage space. The condition is good, except for a small peeling on a part of the spine of the book that serves as the lid. Please note that I have not counted the number of planks, so there may be fewer than 280 pieces. Please be aware of this. I would like to request a no-claims, no-returns transaction.
