Fun little gadget we never knew we needed.
Color: Pink
Who knew keeping our bags and purses could be so easy. Easy to clean once it does it's "job". Doesn't take up much room and works like a charm

Mixed Results - Sauberkugel Clean Ball Review
Color: Bag Petrol
I purchased the Sauberkugel Clean Ball in Teal to help keep my bags clean from dust, dirt, and crumbs, and while it had some positive aspects, I can only give it a moderate 3-star rating due to a few shortcomings.
On the plus side, the concept of the sticky inside ball is ingenious and showed promise. It did manage to pick up some dust and small particles (including glitter) from my purse which was a relief. The teal color is cute and made it easier to spot in a bag.
However, there were some limitations that affected its overall effectiveness.
*It seemed to struggle with picking up certain types of debris, particularly larger crumbs, heavier dirt, and ever some larger glitter/confetti pieces. This inconsistency was a bit disappointing as I had hoped based on the ads for it to be much more effective.
*Another major issue I encountered was the difficulty of opening and cleaning the ball. The design was supposed to make it relatively easy to open and clean (as the ads lead me to believe). However I was unable to get the ball unlatched - which made it quite challenging to clean fully. It was frustrating to wrestle with the ball and being unable open to clean it out fully.
In summary, while the Sauberkugel Clean Ball had its merits and did manage to capture some unwanted particles, it fell short in terms of consistency and ease of use. The struggle to open and clean the ball was a significant drawback for me.

Great item, totally worth it.
Color: Black
I've used this for over a year now in my nice work purse to keep those tiny dirt particles from who-knows-where (you know the ones I mean!) from mysteriously getting in the bottom of of it. It rolls around easily in its plastic case either naturally (without getting goopy or leaky) or rolled by hand. Handiest thing I've ever bought to help keep my purse clean!
