A4 ( 21 x 29.7 cm ) Acid-Free Window Mats for photo frames and picture frames (Pack of 6 mats that will suit inner sizes of 4″x6″, 5″x7″, 6″x8″ & A5)

Description

These bevel-cut, A4 ( 21 x 29.7 cm ) Acid-Free Window Mats ( also called window mounts or simply, mats ) have one rectangular opening each and are available only in the four colours thumbnailed below and as shown above the 'Add to Cart' button.

The Outside is the mat's actual outside size and generally fits inside most picture frames or photo frames of that size. The Inside is the mat's nominal inner hole size and should suit any picture or photo of that size.

Importantly, the inner size openings, or the inside holes of the mats, are never cut to be a certain size, but rather, "to suit" a specific size.  Thus, an A4 opening will not be cut to measure exactly 210 x 297 mm, but rather,  a few millimitres smaller. This creates the necessary clearance to stop the art falling out of the opening. Please do not order or buy these mats if this does not suit your requirements.

Mats are bevel (at an angle) cut, with sharp edges and carry Warning Stickers telling users to be careful when handling the mats. To attach a print or photo to the mat, simply tape it to the back of the mat and then insert the whole assembly into the photo frame or picture frame of choice. With our A4 ( 21 x 29.7 cm ) Acid-Free Window Mats no hand tools are necessary and no fitting or servicing by a picture framer is needed.

Please note that due to variations between computer monitors' RGB colours and mat-boards' CYMK swatches, the rendition of the shown thumbnail colours is approximate only. Further, Colours can vary slightly between milling batches and may be a little cooler, warmer, lighter or darker between production runs.

This can happen, is beyond our control and we cannot guarantee absolute colour accuracy.  Further note that mat openings are never cut exactly to nominal sizes but always a few millimetres smaller. This well-established picture framing practice prevents the artwork from slipping, or falling, out of the holes, or openings. Our  A4 ( 21 x 29.7 cm ) Acid-Free Window Mats are wrapped for cleanliness and your protection.
