The glasses seem to be strong and unlikely to fracture. That's excellent news. The main problem is that the volume labels on these glasses (the reason you purchased them instead of a normal cup) are incorrect. That is, they are far beyond the specified +/- 5% error range. The 1 shot/30 ml line really measures 20ml, resulting in a 30% inaccuracy (see above photo where I filled over the 30ml line and the scale is reading 24g which is 24ml). If you want to pull off a one-shot, aim between the 1 shot and 2 ristretto shot lines.
Decorations: Some shot glasses contain embellishments on the surface, such as rhinestones, metal, and other materials.
It's crucial to know what to look for when ordering shot glasses for a friend or for yourself. They are used for drinking and gathering. Whether or not the glass sees whiskey in its lifespan, you want a one-of-a-kind shot.
