I recently purchased three of these adapters after seeing it at a friend’s. Very unique and hard to find. Coming back tonight to order more. They make loading so easy, no waste, no crawling to find that dropped stuff. Quality borosilicate glass is impressive, ensuring durability and a great experience, like the rest of the selection here. Careful sharing it, though, with any nubes. Can clog stem if pulling too soon, too deep or too hard. The pricing is very reasonable for such high-quality items. Shipping was fast, safe, and discreet, making the whole experience seamless. Highly recommend!
