Boao 4 Pieces Feeding Tube Brushes, Long Pipe Cleaners Straw Cleaning Brushes, 32 Inches Long with Soft Nylon Bristles Head, Suitable for Cleaning Feeding Tubes

I received all 4 items same size where as desperation mentioned different sizes.

Bought these for work to clean tubing in our part-task trainers. They were getting blocked up and affecting the working of the manikins. I halve been looking for some brushes that were small enough in diameter to fit down the tubing. These long, thin brushes are great. They get into the tubing and clean off the dirt and mould that has collected. They are long enough to reach through the majority of the tubes and will hopefully extend the lifespan of these training manikins. Thanks

I have to say I had to get creative with this great set. I have 7 outside water features with pumps, plastic hoses on the pumps I wanted to clean them but never found a way, I saw this set and thinking, great, ordered it and it is the best to clean your hoses or any small, really small, pipe that needs cleaning. It needed to be long which these brushes are. Clean your glass straws also. Empathy for people with the need for a feeding tube but it is nice that they have such a remarkable product they can purchase

Found what I was looking for!!

This worked amazing on my 2011 Rav4 for cleaning out and unclogging the moonroof drain tubes. Fixed both drains in less than 5 minutes. Had the car at dealer all day with a quote of $1700 this was fixed by myself for less than $10. Great product

These brushes were bought to clean tubes used during animal surgery, and they work beautifully. The tubes are various sizes and so are the brushes.
