The discolouration is the residue of a fixing liquid. As soon as coloured textiles are printed, they must first be pre-treated with this liquid. Only then can the colour be anchored in the textile. The substance we use is harmless and certified to ÖKO-TEX Class 1 standards. Experience has shown that the colour fading described by you disappears after the cleaning process.
Please wash the textiles according to our instructions:

• Wash before wearing for the first time
• Maximum washing temperature 30° C
• Do not use liquid detergents
• Do not bleach
• Do not fabric softener
• Do not tumble dry
• Do not iron hot
• Do not dry clean
• Wash and iron inside out

If print or material defects are still recognisable, please contact us with detailed pictures via our [contact form].
Of course, your claim will not be invalidated by the washing process.
