Review: Comfortable, invisible spacer that actually works. - I was able to get a perfect fit with this product! I just received an engagement ring (YAY!), and despite ordering a custom size (my fingers are pretty small, size 4.5) it was still a little loose. I find the coil spacers uncomfortable and my ring spun on my finger which affected the look and comfort of my ring. That led me to this great product! The kit comes with 8 spacers (2 of each size) and I was able to find one to fit my thin band. Make sure to try all the sizes to ensure you're getting the best fit. I also like that this spacer snaps onto the inside of the band so it doesn't cover the diamonds along the side of my ring. If you have issues with the spacer falling off or need a slightly tighter fit, the kit also comes with this rubbery, double-side tape that you stick inside the groove of your spacer. The tape can be tricky to get into the groove of the thinner spacers, but is easy to remove or adjust, and doesn't permanently adhere to your ring. I didn't find that the spacer fell off on it's own ,but I added the tape anyway to make it a little more snug. Overall, I definitely recommend giving this a try. It's comfortable to wear and not clunky like other spacers. Fairly easy to use, and once you have it on, you'll forget it's even there. Review: This product is great, just be sure to size correctly! - I ordered the variety pack of ring adjusters to figure out which size fit best. My ring (and hand in general) is small (size 6), so I anticipated using the XXS size. Surprisingly, this was actually too small, as it didn't clip in correctly and when I cut it to fit, it kept popping out (not the product's fault - just incorrectly sized to the band of my ring). I jumped up a size to the XS (1.5mm - 2.5mm) and it works beautifully - snaps right in and stays there. One thing I will mention, with wear and tear (4 months), and snapping it in and out every day, it does loosen a bit (which is why I think it's nice to have more than one. Also nice to have a backup for those days when your hand randomly swells and you pop it out and accidentally misplace). All in all, it's a great, inexpensive way to secure my ring through the colder months. Will be ordering again in future! ## Features - FITS WOMEN THIN RINGS - Fits Ring Width from 1mm to 4mm, Perfect for Womens Thin Rings.
