Some products on the market may have uneven tile surfaces, slight indentations in the acrylic, or minor stains that affect the overall look and feel.

During the engraving process, some tiles may suffer from misalignment, resulting in overlapping numbers or unintended patterns appearing on the surface.

Some tiles have color residue or adhesive along the edges, leaving a rough texture that's noticeable to the touch — and potentially allowing players to identify certain tiles by feel alone.

On some tiles, the paint doesn't settle evenly within the engraved grooves, resulting in a misaligned appearance that affects the overall look of the set.

On some tiles, the paint within the engraved grooves is insufficient or missing entirely, making it difficult to clearly distinguish the numbers or patterns on the tile face.
