They come in packs of 25.
These are made of polypropylene.
These are usually used for storeing and displaying art prints and are acid free.
This will depend on the nature of the textile piece, but a flat piece of fabric should be able to sit inside a sleeve similar to a piece of paper.
These sleeves are not punched. Seawhite do not manufacture a book specifically for use with these sleeves, but they could be used in any display book or portfolio that doesn't contain rings.
A 20 x 30cm print will fit the A4 plus sleeves.
Dear Sara Maidment
The exact measurements for the A2 sleeves is 43x60cm where an A2 size paper is 42x59cm. I hope this helps to answer your question.
Cass Art
A3 Seawhite Krystal Seal Sleeves are specifically designed to fit inside the A3 Seawhite Archival Boxes.

28th January 2021 | Reviewed by Barry O'Brien | Great acid free, archival quality sleeves for protecting and presenting artwork. Their thin profile means that if you are placing artwork inside them to send off via envelope/mailers etc, they do not unnecessary weight (and £s) but still insulate the art from damage. |

A very useful purchase at a good price, and something I haven't found at other suppliers. These sleeves are just over A3 (a little longer when not sealed) and are clear plastic, not thick but substantial enough not to tear easily. They seal at the end using a sealing strip which is covered with a wax paper strip when supplied, so that you can use them unsealed if you wish without any risk of catching your painting on adhesive. If sealed, they can be opened and closed again (multiple times they say). I use these for both storing and displaying my watercolours, including a simple mount and a backing board in the sleeve. There are too many to frame and hang them all, and this is a safe and cheap solution - I can rotate and swap them into frames whenever I want to. |
