The Original Degrē Coaster (Set of 6, Winter Salad) by LINE+ARC. 10mm Thick Dishwasher Safe Stain-Resistant Outdoor Coffee Table Silicone Modern Hexagon MidCentury Cup Drink Non-Absorbent Rubber

The coasters look and feel great. They work well overall but the angled edges can make it slightly unstable if the glass isn't placed directly into the middle of the coaster.

REALLY, REALLY wanted to like these a lot. Pros: 1. They're beautiful. Virtually a work of art! 2. They're well made, really "solid." 3. Love the ridges, hold liquids that might sweat or spill off a cup edge. They're also staggered toward the center so that any overflowing liquid will travel to the bottom center of the coaster giving more "capacity" before spilling onto a table. 4. Easy to clean. I drink tea regularly, have not had any stain issues as others have reported (but then again, if I have gotten some tea on one of them, I blot it up quickly). This is sounding pretty 5 star so far. But then the cons, size and stability, come up. I've been using them with a variety of my tea mugs, including Yeti insulated mugs for quiet weekends relaxing and sipping. I have the short, wide 14 oz and the tall, narrow 24 oz "Rambler." It annoys me that Yeti doesn't put a non-scratch rubbery base on the mugs - first to protect things you might put it on and second to make them quiet. They make a ringing noise putting them down on anything solid. That's a separate issue entirely, but that's why I bought these coasters, hoping to muffle the noise and protect the table. The problem I've found is the coaster size - they're smaller than other square and round stone coasters I have. On a larger coaster, you don't have to worry about centering the mug/cup, as I find that I have to do with these. But more of an issue is the fact that the bottom edge of the coaster is "undercut." Please see the pictures. The central part of the coaster bottom is nice and flat (= stable), but then the molding makes a beautiful, "cut crystal" appearance which has the effect of making the outer edge of the coaster less stable (because it no longer contacts the table). The functional impact is that you really have to pay attention to where you put your mug/cup. Too far to the edge of the coaster and the mug isn't stable, particularly if it's full and heavy. The mug can push down on that undercut area and since it isn't supported by the table, it can tip over, at least in theory. The picture I've attached that looks a bit like the Leaning Tower is with a completely empty mug; just the weight of the mug alone can push the edge of the coaster down when it's placed off-center. Fortunately I haven't had one fall and spill, but that's because I'm paying close attention now to exactly where I place the mug onto the coaster. And frankly, I don't really want to have to place much thought into the use of a coaster! They absolutely wouldn't look as pretty if these were molded with a completely flat bottom, but they'd serve their function better if they did. Just take your needs and habits into account. But this is something to consider, to me. I paid full price, with my own money, for the product so these are my unbiased observations. Hope they can help someone.

3 month update: No stains! These coasters are so easy to clean, dry, and reuse. Ceramic, cork, and fabric coasters absorb liquid and can leave faint stains (see my stain test with coffee, orange juice, turmeric, and sriracha).The Degre coasters from Line and Arc arrived ahead of schedule and were beautifully packaged. After laying them out, I saw the full color range within the set more clearly and the shades are wonderful. The colors perfectly complement our wooden dining table giving it modern but earthy vibe.The coasters have a great feel to them. Very well made - the silicone is tough, durable, and feels rugged (not flimsy/flexible). They also have a soft surface texture so they won't leave any marks/scratches on our dining table (unlike stone/ceramic coasters). I like the weight as well - not too heavy while providing enough stability. The ridges add great visual appeal but also help trap condensation and the slightly concave shape ensures liquid will not drip/spill off the coaster.As a bonus, we're able to use 3-6 together as a mini trivet for hot pots/pans as well!

We’ve bemoaned average coasters for years because they stick to our glasses if there’s any condensation, then fall & break or scratch something. We just got these & we LOVE them! The ridges, material, and slight concave shape means they are certified stick-free! Heavy enough to stay in place but won’t scratch any surfaces. The different shades look nice on our furniture too. We have another order coming in blue.

These coaster just arrived and they look and feel awesome however I spilled some tea on one of them overnight and now they're stained. I tried washing them with various soaps, water temps and even ran it through the dishwasher and can't get it out. It wasn't even a dark colored tea. I wouldn't recommend this to anyone :(
