First of all, I bought these envelopes because I can't find any other kind of vertical
"double-opening" envelopes anywhere. So I knew I wouldn't quite like them because I was looking for
vertical envelopes with both openings on the same side (top and bottom) but in this case is has one
opening on top and the other on the bottom of the opposite site. But that's just my issue, and it
doesn't mind.
The problems:
- Design: When you look inside the envelopes you can
clearly see the glued piece of paper that leads to "the other side", and even though when looking
from one of the openings can look quite "convincing", the other opening has some unglued areas and
it buckles when you try to show the envelope empty so you can have a glimpse into the other side
- Partitions: just to mention (cause I forgot) that the ad states that partitions should
not be used with cards because it gets too thick.
- Slits: straight slits look horrible
with these envelopes... They buckle in a strange way when you open the envelope, looks unaesthetic
and it's not smooth to close. It should have been a shorter half-moon slit just as in the other
tyvek envelopes by Alan Wong, or even better: no slit at all...
Conclusion: keep in mind
that if handled well you can use them in performance and it would fly by. But for that price I
expected a superior product. I would even prefer crafting myself Mark Chandaue's envelopes.
You can take care of the visible flap. Take a glue stick (strong glue) and a toothpick. Using the toothpick glue the back of the inner flap which is loose. Press the flap against the back of the envelope and the visible flap become invisible and matches the top seam of the outside flap.
As for the shape of the flap and the horizontal slit, I really don't have a problem.
As for the "unaesthetic" look of the slit, I really don't think the spectator gets much of a look at it. You pull out a piece of paper or a card (which does work in the envelopes) and that's where the attention is.
