Keep in mind that laser engraved designs are not truly black, their color depends of the stainless steel of the tumbler underneath the powder or paint coat layer. Laser engraving is a precise process but small imperfections or variations may occur due to the nature of the engraving process and the medium being engraved. Examples of these imperfections may include: minor inconsistencies in depth, variation in lettering or design among another minor flaws. These are not considered defects due to the fact they make are inherent to the laser engraving process.
