[This review was collected as part of a promotion.] I took these to work (at a very busy vet clinic) everyone loved them, I especially appreciate the lines on them. They stuck great to everything we applied them to and we didnt lose any important notes!

[This review was collected as part of a promotion.] What's not to love? These Post-its are from the "A World of Color" collection; the Rio De Janeiro collection. Super fun colors that I can see from across the room. I like this size. The 4x4 inch size is bigger than the standard and perfect size for leaving notes to myself in my filing system at work. I love having lines on the paper itself. It keeps my notes from sloping and looking sloppy! This collection is also "Super Sticky," which works well when I need them to stick to a variety of surfaces - my computer monitor, my walls, my file folders, etc. I received this package of Post-its at no cost from 3M to use and review.

[This review was collected as part of a promotion.] I received a free sample from 3m, and am very pleased with the pads. The larger size is easier to write on and the horizontal lines make it easy to fit more in and keep the writing neat. The back of each sheet has a larger sticky area so the sheets are securely stuck to surfaces. The colors are fun and vibrate. Overall it's the same great quality you would expect from 3m.

[This review was collected as part of a promotion.] I love the Rio de Janeiro 4x4 Post It Notes! Beautiful colors make tracking task reminders much more fun. The larger size and lines allows me to write more about my reminder or task, and helps me stay neat rather than just quickly writing some messy note to myself.

[This review was collected as part of a promotion.] These post-its stick well to any surface. I like this size for making more detailed lists and/or putting complete thoughts to paper, something you can't do on the smaller sizes. The only thing I don't like is the colors are too vivid and make reading your notes a little difficult in less than ideal lighting.

[This review was collected as part of a promotion.] The bright, fun colors of the Rio de Janeiro Post-it collection are bound to attract your attention so you won't forget those important memos or shopping lists, and being Super Sticky allows you to place them in prominent places safely, like walls or the fridge, with no marring or resdue when removed. The generous 4x4 size is great for tasks which require more space, such as listing the contents of storage boxes, with extra adhesive power to adhere to uneven or textured surfaces, like locking lid totes, with ease. In fact, that's one of the things I am using mine for, to itemize storage containers in my basement and attic. What a timesaver! The product not only helps you but the environment, too… the adhesive is plant-based and paper made from sustainably sourced forests. It's a win-win situation! 3M has kindly provided me with a free sample of this product in exchange for my honest review.

[This review was collected as part of a promotion.] I like these super sticky notes for lists, the lines are very helpful and they stick and re-stick as needed. The only reason I didn't give five stars is because of the colors and absorbency. The pink is a little harsh on the eyes and my ink smudged a bit if I didn't let it dry for a while.

[This review was collected as part of a promotion.] These post-its are a bit bigger (4x4) compared to the common post-its. The bright Rio de Janeiro collection adds a pop of color to your work space! I mean you can't help but be happy when you look at those colors! These are perfect for making a to-do list, big enough to doodle or jot down ideas, and excellent for leaving a note for someone. 3M gave me a sample of this product to evaluate.

I Love all post it notes but these are my all time favorite!! The lines make it so easy to use for lists and is the perfect size for everyday use. I am constantly writing notes and rewriting and with these I stick them were I need them and I no longer lose my lists!!

[This review was collected as part of a promotion.] I received this product free in exchange for my honest opinions. The 4x4 lined notes give a little more space than your typical 3x3. Plus the lined notes make writing a list a cinch. My one complaint is the lines on the blue are very difficult to see. I've attached a photo showing what blue ink, black ink, and pencil look like on each color.
