worked as it is supposed to. First time I've ever used puzzle glue so I did end up putting on two coats (If I had just spread it a bit heaver (maybe used a brush instead of the tool I might have got away with just one, but not a problem doing 2). You do (or should) need to attach it to a backing and I followed on of the online video guys to do so which I would recommend. Easy to use and do,

I used this, a double layer on the front of the puzzle, and it worked perfectly. I wish it had the brush, Instead of the small spatula thing, it got a bit messy, but cleans up quickly with soap and water.

Excellent glue that works well on puzzle. Clear and hold the pieces well together. The amount of glue in the container is a barely enough for a 1000 piece puzzle. May need more for a bigger one.

I don't know what that one star review is complaining about. When I was kid we had done one and it fell apart in the picture frame so I put a lot of layers on to be sure but it wasn't necessary. some people complained about the glue taking away the color and ruining the puzzle but I put the glue on the back of the puzzle and it worked great. we're extremely happy with how it turned. lots of glue in such a small bottle. 11×15 inch puzzle, 4 layers or so.

really like this glue better than puzzle piece shaped one

i have used this product before and has done very well. i was so glad to fine on line. do to not fining in store.

I used this for my first jigsaw puzzle gluing.

This is the best glue! It applies easily especially with the plastic tool. It dries with a clear finish, and does not ruin the image of the puzzle!

gets the job done

Haven't tried it yet but will be sufficient for my gluing a jigsaw with no desire it's perfect. SO—— don't you love when marketing takes pics to make items look large? Fools deceive, to fool you. Always looking for ways to deceive. 4oz yes, but such close-ups taken to deceive. No sitting it beside a teacup to show it's true size. That would be too honest.
