4 Inches See-Through Archival Polyester Mounting Strips. Acid-Free, Framing Photos, Hinge-Less, Sturdy, Safe, Conservation, Easy, Artwork, Craft, DIY. (Pack of 60)

They work amazingly well. Went to frame a signed band poster and needed a way to secure the poster and center it in the matt, without putting any tape on it, which devalues any artwork. These are perfect, work very well and are very easy to use.

Really useful mounting strips. I don't like the idea of getting adhesive on my artwork and these allow me to mount illustration board inside of a mat easily without having to use tape on it. They are high quality and stick well. Would buy again.

where have these been all my life????

These are pretty good and serve my purposes well. You can cut them into smaller sections which is very handy. Matting an 8x10? I cut one piece into thirds and place two of those pieces on every side. Holds the artwork nicely. My only gripe is that I wish they weren't so thick. They create a space between the mat and backing board that I wish wasn't there. Sure, I'm going to frame it, put it become glass and use a dust cover. Still, they're a tad thick. Having said that, I did just order another box!

I use these for mounting backgrounds to animation cels. They make a very good archival mount and can be cut in half, if the situation warrants it. I will either mount a laser color copy, an original watercolor background, or an archival acid-free foam colored background with these. One on the top of the sheet and one on the bottom is all that is needed, unless the paper is extremely thin. The mounts have a catch area in the first 1/16 inch or so of the foam backing where regular paper can be forced in for a friction fit. In most cases, though, just having the clear plastic covering the backing sheet is enough to keep it in place. Both the foam and the watercolor backgrounds are thick enough to fit under the plastic snugly. The strips are 4 inches wide, which is too much for all but the largest of backing sheets. I generally cut them into 2" pieces for mounting and have even had to snip off up to half of the glue surface because the mounted sheet is so close in size to the backing board. It can handle up to half of the glue pad removed without losing too much of its holding ability, especially after a top mat is place over it to keep it in contact with the back board. For my purposes, these strips are perfect. They not only hold the backing sheet to the back board, but they also force the mat on top of them to stand off by about 1/32" extra from the mounted sheet. This reduces the chance of adhesion between the sheets over time. In addition, I mount a lot of anime cels, which require an extra mat sheet behind them to keep an air space between the paint on the back of the cel and the background behind it. The mounting strips increase that space by a precious couple of millimeters. I have bought and used at least 6 boxes in the past year and find that they are expensive, but worth it in the long run.

I needed to secure an antique etching to a new mat. I didn't want to use tape or anything that would damage the artwork - these strips were the perfect solution.

Great product and easy to use. Wish I'd discovered these years ago. What a difference mounting a photo or drawing using this system. Highly recommend. A+

They weren't super easy to work with, you really have to know where you want them to be placed before touching the backing or matting, as they stick very quickly and damage the paper if you try to remove them. They also don't hold pictures close to the matting or backing if they are at all wavy. I realize that isn't what they are for, but just fyi.
