This is THE dish for vertical dabs.
The Nectar Collector Parabolic Bird Feeder Dish’s innovative design keeps your oil in the center and stops it from spreading into corners or edges where your oil gets trapped. The food grade, high-temp silicone lid locks securely in place on the borosilicate glass dish for easy pocketability.
Fantastic crucible. Had one for three years and it served me wonderfully. Even traveling. Unfortunately it died today (my fault) so I immediately ordered another. This is the perfect dish for any collector.
