60 Pieces Self Adhesive Cork Coasters Squares/Round 4 x 4 Cork Mats Backing Sheets for DIY Coasters Crafts Backing Tiles Supplies(Square)

Yes, they are paper thin but worked out perfectly as backing for my 4x4 ceramic tile coasters. I had no issues removing the backing, but I did use my craft grabber tweezers to lift an end a peel. Super sticky and adhered without any additional adhesive. Would purchase again.

Made some personalized coasters for a friends retirement. These made the coasters non-slip as the coasters were black matte and absolutely smooth on both sides making them very easy to slip if not placed properly on a surface. The tiles were commemorate a special life event and thus needed to double up as a "display" piece as well. Adding these cork backings really made a HUGE difference. The tiles looked more elegant in my opinion and allowed for multi use. Now the tiles would be non-slip if used as a coaster! If I had to find anything "negative" about them, it's the initial impression I had, that they were too thin and thus the removal backing was more of a challenge to remove. Tried separate it with my finger nail and that too proved to be a challenge. I ended up using the weeding tool for my crafting and being able to subtly "stab" the paper backing made life of removing these sheets a whole lot easier and quicker! Adhering them to the tile was easy once centered and once placed, they stayed put!

Right out of the box I was surprised how thin these were. The rounded corners look nicer than straight edges. They are super sticky and stuck really well to the back of a tile. I had to remove one and although I did manage to get it off entirely, it wasn't easy - so the adhesion is really good. Because they are so thin, they are flexible and fit well over any bumps and grooves on the back of a tile. So unless you have a perfectly flat surface to adhere these to, I would not get anything thicker.

I am putting these on the backs of 4" wooden squares to make coasters. The cork is square is 3.75". There is a gap that I would prefer not be there. They are thinner than others I have ordered, almost 2mm thick.

These are great to apply over an existing coaster. They are perfectly cut, smooth and pliable making for easy adhesion to your surface. PLEASE NOTE: These are veneers to provide a cork surface to an existing coaster, they are not actual standard coasters. I actually used my on top of a cork square to provide a more finished, profession appearance to a DIY project.They are a great value for the money

Works perfectly for square 4" wood plaques. Leaves 1/8" border all around. Helps cover any rough wood areas and helps with slipping.

I bought these to put as backing on wooden drink coasters. They work and stick fine, but they are quite thin. I would have preferred a thicker mat.

this item is awesome. I use it to back my drink coasters to keep avoid scratching tables.
