A soft light blue evokes a clear summer sky and exudes a sense of calm and lightness. Our 155 x 155 mm envelopes are therefore the perfect choice for presenting your personal messages in a friendly and modern way. Thanks to their distinctive square shape, these light blue envelopes stand out clearly from the usual daily mail and immediately capture the recipient’s interest.
Whether for christening invitations, heartfelt birth announcements, or simply a special greeting for friends—this format gives every card a unique touch.
The high-quality 120 g/m² paper makes the envelope sturdy yet light enough to be mailed as a standard letter. Thanks to the traditional water-activated adhesive, the pointed flap can be securely sealed after moistening, which also ensures the envelopes can be stored for a long time. If you prefer a different shade, you can also discover other light blue envelopes in our selection or search specifically for other colors in the 15.5 x 15.5 cm format. In our category for square envelopes, you’ll also find plenty of additional inspiration for your correspondence.
