10. Sweetzer & Orange


A4 White Envelopes Self Seal. 100x Envelope and Box. Mailing Envelopes 4x6 4.25 x 6.25 in. Thick 150gsm Self Sealing Envelopes, Blank 4x6 Envelopes for Invitations and Wedding, Sweetzer & Orange

Sweetzer & Orange #ad - So why not try them now, christmas cards or even special business envelopes, risk free with our 12-Month Guarantee. While others open in the post, Sweetzer & Orange Self Adhesive Envelopes stay shut for the whole journey. For wedding or baby shower invites, save the date, greeting cards, you can feel good knowing whoever receives it will notice your attention to detail.

And as for how much you can cram in? Well, each A4 envelope will easily fit up to 9 regular photos. These thick self seal invitation envelopes come nestled in their own sturdy box. But what you can’t see is how crazy strong these self stick envelopes are. Or those ultra-thin ones that seem almost transparent. And they’re made for regular postage when you don’t overstuff them. More value for money: everyone agrees a set of 100 4x6 white envelopes is great value.

But when they’re shrink wrapped and become tattered and lost over time, that ‘value for money’ you expect, is now the value you get, that value obviously diminishes. Because you’re using them for some very special cards, so calligraphy pens love them, photos and invitations you’ll appreciate our matte, and you can even pop them in your printer!. Thicker than most: you’ve probably seen thinner 120gsm blank envelopes today. In fact they’re 4. 25 inches x 6.
