good product - junk bottle! i took the cap off a brand new bottle and tried to squeeze 1 drop onto fly, and the nozzle came off the bottle dumping the entire contents into my fly box.just like someone unscrewed the lid on a salt shaker.looking closely at the nozzle,to see what went wrong, it appears that it merely presses onto bottle, no threads ,no glue.i needed to use a 9/32 deep well socket to push nozzle onto bottle, witch took considerable effort to finally snap into place. this should have been done at the manufacturer. its a wonder why they don't leak during shipping. my last bottle lasted more than 15 years until the plastic bottle got brittle and cracked. now that i have gone through this, i am starting to recall reading about this back then. be sure and check your bottle, so you don't have a mess like me. my flies should float for 50 years and my tying bench is now waterproof. be careful, you have been warned.
