Nice brown letterbox boxes, available in 3 sizes.
These boxes are specially made to send small packages. Because of their height, they are suitable for a letterbox package. This way you can keep shipping costs low.
The beauty of these boxes is that they have a real BIO appearance. In addition, the box can simply be used in the old paper bin / container after use. In this way you contribute to a clean environment.
The boxes are equipped with a good flap closure and together with the "side arms" they ensure that the box is closed properly.
