Boao Wax Melt Liners Reusable Wax Warmer Containers Leakproof Cups for Scented Candle, Paper Holders for Electric Pluggable Melter and Burner(Black,50 Pieces)

I have one of the commonly available Better Homes & Gardens melt warmers that Walmart carries, and the silicone liners I've tried don't set all the way down on the bottom of the wax reservoir because the sides splay out too much, and so the wax doesn't melt. These cardboard ones are "adjustable" and so they work great!Side by side, these and the silicone ones are the same dimensions, but whereas the silicone ones hold their shape no matter what--cuz silicone, duh--you can collapse the pleats of these cardboard liners between the circle of your thumb and pointer finger so that the sides of the liner stand up straighter and splay less, which in turn allows the liner to set flush on the bottom of the wax reservoir. Don't be afraid to over-squeeze; it will relax a little after you put it in the reservoir, but will generally hold its less splayed shape. (I hope all this makes sense. I'm on my desktop and can't include a photo at the moment.)These are also reusable for a loooooong time. I think I've only thrown away one in the several years I've been using these because it got irredeemably cruddy over time--but I think that may have been due to the particular melt scent I'd been using, as it hasn't happened since.Also, as others have said, hardened wax pops right out. It might require a bit of loosening by fiddling with the sides, but this is minimal. My "system" is to use two of these in a tag-team manner: one in the warmer doing its smelly thing, and the other one set off to the side letting the spent wax harden. When the one in the warmer needs to be changed, I set IT off to the side to let its wax harden, and replace it with the now-emptied one that previously had the hardened wax in it.These are very thick, sturdy cardboard, and so would easily hold liquid potpourri as well as wax cubes/crumbles. As far as wax cubes, these liners could easily hold 4 wax cubes, maybe even 5 (though why you'd want to use that many, I'm not sure). That said, for me personally, 3 would be a comfortable max to prevent sloshing if the warmer got bumped. It should be noted that these do have rigid, flat bottoms, and so wouldn't work well for warmers with the curved bowl-shaped reservoir because not enough of the base would be directly on the heated surface and the wax wouldn't melt.I love these things. For decades, I had a love-hate relationship with wax melt warmers. I loved the scent possibilities w/o worrying about monitoring a burning candle, but hated struggling to remove the spent wax. As others have said, these are a game changer, for sure.

These lil cups are awesome. They save time changing scents. They don't get hot to the touch so you can remove without waiting for the wax to cool and harden. I reuse them several times before discarding. No more wiping or scraping used wax from your warmer. Definitely recommend.

Helps me keep my place smelling fresh. No problems. Slight cracking after multiple uses but other than that it is great.

They are easy to lift out and toss. No need to scrape wax out of your warmer! I do feel though that the wax melts don’t quite smell as strong with these in the warmer. Small trade off for not having to figure out an efficient way to remove melted wax.

These work great - I think my wax did melt a little slower than normal while using it (and my warmer isn't super strong to begin with), but it did still melt, which is all I care about. They're pretty stiff - I don't know why I was expecting them to feel like cupcake liners lol. You can definitely re-use them, the wax pops out easily after cooling, so I expect I won't have to get more for a really, really long time, if ever. I can't really imagine a scenario in which you'd ever need more than the minimum amount of these they sell. I feel very comfortable recommending these.

This was just what I needed. I have a very old warmer and never felt confident to even leave the room when it was on. I feel very confident wax won't be all over the place with these inserts. Very affordable for the peace of mind.

Got a big package of these for wax melts so cleanup is easy.They should last me a very long time and they fit in my various scent pots and candle holders because they're so flexible

I love these little things as they make it easier to swap scents, but you're gonna wanna double up! They will leak through just one and get all over your oil warmer surface.

These liners are genius. They make changing fragrances effortless. No messy wax to deal with and the melting pan stays clean. They even work in my small plug-in warmer. I just give the liner a bit of a squeeze to tighten the folds and it fits perfectly. And I haven't found them to affect the fragrance at all. Totally recommend them!

I thought this would be paper but I was pleasantly surprised to find it was reinforced plastic/ card. I've used them over and over and they are great. I bought 25 but I think these will last a very long time as they are reusable. Excellent value for money too.

No more having to clean the wax from my burners. Can be used multiple times too.

They are extremely useful and are saving me a fortune on replacement glass, I havn't had one glass cracked while using these. One can be reused numerous times and are extremely easy to pop out the wax and replace. Albeit if using low quality wax I doubt they would help with the quality of the smell, otherwise highly recommend.

Thes are so easy to use, change your wax with no mess. They are reusable too
