Yaomiao 6 Pieces Silicone Anti Slip Ring Non-Skid Band Ring Soft Protection Sleeve 25 x 17 mm Bulb Glass Silicone Ring (Assorted Color)

fits a large tank well. smok tfv18. didn’t deform or anything or lose color stretching over tank. super easy to put on and stays put. not a huge fan of colors so i’m rocking the black for now but they all look good if you like x color. i dropped the mod from about 5 foot off the ground straight onto rocky asphalt/pavement and it chipped the hell out of the device and metal parts of the tank but the glass didn’t even get scratched. i’ve dropped it a couple times inside on tile and no problems there either. i doubt it would withstand a 20 foot drop but as far as im concerned this is a great product that works exactly as it’s designed to.

Not really silicon, more of a rubber. Don't stretch to well. Will see how long they last. Have a silicon one that works great, but couldn't find them anywhere, so trying these. Time will tell.

Exactly what I needed to protect the glass on my bubble. Slips right on and fits snug. Several color options so I could share with others. I do wish the rubber was just a tad thicker to provide additional peace of mind. But overall a great product

Worked great to keep my vape glass from breaking from random drops. Obviously if you drop it from too high there’s no way to save it. Great product!

Decent quality, just a little small for my TFV18
