Generic AstrocapsNY Popper Topper Leakproof Aroma Bottle Cap - Black USA Sized 19.5mm Thread

Works well, easy to use, no spills

I have had this only a few months and when I went to change the bottle the inside piece with the grooves came out and caused me to spill the bottle. Piece of crap and not worth the money at all.

You will get the best hit / sniff of poppers but with this lid on - very easy to spill.

Easy to use, will work for some bottles, others not so be sure to pay attention to what you buy vs what this will thread to. Fits easily into nostrils and close for non use. Best fit and function so far!

This is super easy to use, and fits right on. There is a LITTLE leakage, just just have to be careful and be sure the seal is all the way closed.

It works good but it's not leak proof. It will also the switch sticks if you haven't used it in a few days.

The Astro Cap does work as intended and fits securely on bottle threads, with multiple sizes available for convenience if you own different bottles. However, the quality is where it falls short.I purchased this cap a few months ago, and recently, it began to fall apart, becoming unusable and beyond repair. This seems to stem from the low-quality 3D-printed material used in its construction.I’ve tried reaching out to the seller several times through their website to address these issues but have yet to receive a response.Ultimately, you’re paying for a piece of plastic that, based on my experience, won’t hold up to regular use for more than a few months. For the price, the durability just isn’t there.

I have been looking for a quality cap for a while and I finally found one. So far it has been leak proof and the design seems durable at the moment. I finally have a product that I can stuff in my bag without fear of leakage.Will provide an update on the durability.
