DuPont Tyvek 55gm A4 - Pack of 20 Sheets (8.3" X 11.7") - ships from the USA

There was a problem with the shipping, but I was kept in the loop all the way and in the end it was only 1 day past the original delivery date. I have no complaints!!! Works perfectly, so impressed!!

great for album making

I make stencils with these. They are great! No tearing or ripping. Cuts clean.

These Tyveck A4 sheets are great for making my junk journals these sheets are great for supporting the spine of the journals, worth the purchase.

Like another reviewer here, I used these as part of a gas exchange system for my jars of liquid culture, and will later use them to allow for fresh air exchange of grainspawn. They smelled a bit hot when I took the hars out of the pressure cooker, but they held up and were very easily pierced by the inoculation needle. Popped a bit of micropore tape over it and now 2 days in my spores are already germinating and mycelial hyphae is floating around in the honey water! Very satisfied. Protip: only fill your LC jars a bit over half-way full if you don't have a magnetic stirrer. You need the extra splash buffer room if you're going to be agitating them by hand (moving the jars in a circle or something, not opening them and sticking a spoon in there).
