RAL Card Classic single sheet: If available we will send RAL Original Classic single sheet. If the single sheets A4 are in arrears with RAL, we send handmade sheets, these are NOT RAL certified. It often happens that RAL cannot deliver. Lachenmeier Farben can always deliver any RAL Uni-colour within a few days! Attention: RAL Original A4 are mostly perforated for folders. Handmade A4 are always without holes!
