OD 6mm Ruby Pearls set, 10 packed, Black Color (Black)

This is not real quartz. I did a simple scratch test and they all failed.

$6 for 10 on amazon or $10 for 1 at a glass shop

"heat resistant wont crack" cracked day 3. chinese junk.

I bought these for dry herb. Figured they could even the vape. I wished.They don't. Wasted money. Top, bottom, or anywhere in between.

I started with 10 now I have 4 after 1.5 weeksThey explode when heated or crumble when cold.

I love black balls
