Herco HE186SI Spit Balls Nettoyant à instrument en laiton

These are very cool just make sure you get the right size for trumpet or trombone

Works as a quick swab out in between cleanings.

does the job

I asked my local music store for this product, and was told that their cost (theirs, not the retail price) from their wholesaler was three times what the price on Amazon was.If you haven't used these, give them a try. Great to use once per week between regular soap and water cleanings.Be sure to poke the ball into your leadpipe with a pen or pencil. Only placing it just past the mouthpiece will not give you adequate pressure to blow it through the tubing.

Not to sure how this works if you blow hard it’s out in a second if you look threw the slide it just the same just a bit wet but will stick with it but I don’t think I will buy more sorry
