Due to changes in temperature and humidity, the board will warp, so the thickness has an error of plus or minus 0.5mm. Moreover, each wood board has different wood grains and wood colors, so there will be color differences between each wood board. There is no designated grain and color selection when purchasing, and we will not help customers choose products.木板因應氣温濕度改變而翹曲或厚度有正負0.5mm 的誤差，而且每塊木板有不同的木紋及木色，因此每塊木板之間會有色差，購買時不設指定紋路及顏色選擇，亦不設代客選購。 The thickness and size of all products are subject to the actual product.全部產品的厚度及尺寸以實物為準。
