My son used this in mills park middle school band and this is a great product for trombones

For my part, I have found that the Yamaha brand slide cream has consistently made my trombone slides very smooth and very quiet.

This works amazingly well with everything.

And very little of the cream is actually required to achieve an effective result.

As a player of nearly twenty years, I highly recommend to any trombonists to give this product a try and see if it works for you as well as it has for myself.

I have used this cream in the past, it is reliable and effective

Just be sure that you have a misting bottle as the cream requires water to function at optimal performance

Probably not the best, but great for the price, one container lasts forever.
