Highly recommend
Color: Black
I love these so much. They make the perfect stocking stuffer but as a chronically messy person, I love throwing them in my purse or backpack. They pick up so much and are really easy to wash off.

Clean Your Purse
Color: Pink
This ball is pretty cool. It acts like a lint roller inside your purse getting all the dirt, crumbs, & lint that accumulates at the bottom. When it's looking nasty, you can rinse it off in the sink & it's good to go back in your purse. It's one of my best Amazon purchases and I will probably buy again if/when the sticky wears off or having a spare on hand.

Value for money
Color: Blue
This definitely is something to have. Used it a lot while travelling and for office use as well. It takes out all the gunk from the bag and is easy to clean as well

Used for a year.
Color: Black
Had this in a back pack for a year and wow. The dirt collected is kinda shocking. I will buy more of these for different bags!

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
