Very sturdy
Very pleased with these envelopes. Much sturdier than the ones I have bought from my local post office, and cheaper! I bought them for posting artwork and they are super. I also find the peel and stick closure very convenient.

Justo lo que buscaba, resistentes pero ligeros. Es dificilísimo comprar este tipo de sobres en packs de pocas unidades y, aunque los uso a menudo, no necesito comprar 100 de golpe y hacer el consiguiente desembolso.Repetiré compra sin duda.

Bon produit et conforme à sa description. Les enveloppes ont un dos en carton rigide pour protéger le contenu. Une enveloppe pèse environ 25g ce qui est un peu lourd si vous devez obtenir un total de moins de 100g pour payer moins cher selon les tarifs La Poste. C'est le seul bémol que je vois. Très bon produit, je recommande.

Perfette; le uso ormai da anni e sono ottime basta solo assicurarsi che i fogli spediti siano messi in una pellicola impermeabile nel caso in cui i corrieri non siano abbastanza attenti

Soy ilustradora y pintora, los he usado para enviar tanto láminas como originales y estoy muy satisfecha, parecen haber llegado a su destino sanos y salvos. El pegamento de la solapa es muy fuerte, no se podrían abrir accidentalmente. Los volveré a pedir y abandonar de una vez los sobres con plástico de burbujas.
