QS01 The Pattern Pen. A fascinating triangular structure characterises the casing surface of the new QS01. The pattern is introduced in the injection moulding into the surface of the casing and is an authentic part of the writing instrument. The smooth minimalistic clip is located above the casing and in combination with the three-dimensional surface strongly draws attention to the logo. With every movement and every change of light the faceted surface structure presents itself differently to the eye over and over again. Available in 11 colours. Also available in matt finish. Metal button available at extra cost.
