I’ve had the bulk reef supply super glue bottle for a pretty long time and the glue itself doesn’t go bad on it. It’s the cap itself that just gets glued on over time. I couldn’t find the cap on BRS, but I found it on another website. I’m sure the website also has the bottle itself for cheap if anyone was curious. I’ll leave the link below, just thought I’d share. https://www.containerandpackaging.com/products/spouted-cap/L413
