YOKFUN Anti Lost Metal Necklace Pendant, for Office/Daily/Sport,8 pcs Rubber Rings. (Keel Chain Black)

This is a tough chain, rubber rings are solid as well. Helpful to never lose any of the vaped again!!

I got this for a friend who constantly loses her Vuse, which causes an entire meltdown no matter where we are. This has saved us from arguments, meltdowns, and fights. She wears it every day, and is slim enough to wear under her clothes if she wants.

Worked great, saves me money, because I kept leaving them on counters, and losing them...

Holds my husbands electric cigarette great

The chain is durable I like it

This is great! I got it from my boyfriend who loses his Juul constantly and it’s been a big help!

these worked well with my caliburn

I was really worried initially that this would not work for my 510 thread vape pens, but I have to say I'm pleasantly surprised!This comes with many different sizes of silicone rings to fit almost any size battery or cart. I haven't lost my pen since this came in, and I have already ordered one as a gift.Great product!
