8sanlione Car Cup Holder Coaster, 4 Pack 2.75 Inch Diameter Non-Slip Universal Insert Coaster, Durable, Suitable for Most Car Interior, Car Accessory for Women Men (Black)

Every time I take my cup out the coaster comes out as well. I use an insulated metal cup. It's not condensation that make the coaster stick to the bottom of my cup. I've cleaned the coaster and cup many times, so it isn't something sticky on either item.

I thought that all cup holders in cars were standard size I was wrong

Should have some sort of sticky backing to hold in place

They description stated it was compatible for my vehicle and it's not. They are too small.

It's cool. Saves messes on the car. Check sizes
