Question: What are the dimensions of the round coasters?
Document: I use the round coasters for drawing and coloring Mandelas (round zentangles) and they work well for that. Don't like what you did? Flip them over and try again.
Not what I expected at all. Just round pieces of heavyweight cardboard. I would not trust these to keep water from soaking through onto my end tables. Planning to return.
Used the coasters as a way for our wedding guests to share advice, words of wisdom, draw us pictures, etc.
These are handy coasters. let dry and you can reuse them or toss when dirty. LOL--I also bought permanent markers for doodlers. You don't need a bar to use these.
We use these coasters every day for ourselves, and for guests. Everyone mentions how easy they are for slight spills and for disposal. It eliminates the "ring" by placing them on existing decorative coasters, and saves slate and marble from stains. We love them for parties.
These coasters are wonderful for drawing on with Sakura Micron pens, as well as other needlepoint pens. They are heavy enough to produce Zendalas. I have suggested these to other Zentangle artists. I have no idea how they perform as bar coasters, as I do not use them for this purpose.
These are perfect if you're looking for  blank cardboard coasters, which I was.They are perfect for printing onto for  a wedding, or birthday, or any sort of craft project.Just white cardboard cut into a circle. They are not plates. They are not frisbees. Just plain white cardboard cut into a circle.
We have a bed and breakfast, and nice furniture to protect, so we put these in every room and are happy with the results. They are fairly heavy weight, and will absorb moisture well
Using it for Votive Candles and Luster Gems Centerpieces then wrapped in Tulle. It's perfect for centerpieces project. It's also inexpensive
These are great ... they absorb the moister of cold drinks beautifully. I couldn't be more satisfied with this purchase.
