[This review was collected as part of a promotion.] I received this from 3M to test and it really comes in handy for me. They are there for me when I need to write something down and perfect for leaving notes to others. The colors are bright and cheery and I love the lines, as I don't write very straight without them Great product.

[This review was collected as part of a promotion.] I recieved this as a free sample and opinions are all my own. I love these post its. They are brightly colored which just puts you in a good mood. It's nice that they have lines and that they are larger than standard post its.

[This review was collected as part of a promotion.] These are a great size for a larger note. Plus the colors are vibrant! Really like that they can be re-postioned and they still stick (the knockoffs really can't do that). I volunteer to evaluate products for 3M and received this as a sample. Glad I was selected!

[This review was collected as part of a promotion.] In general, I love Post-its anyway, but these are even better than the normal ones. The lines are useful for short lists, and the super sticky plant-based glue is icing on the cake (they stick well and leave no residue!). The colours are a great bonus, too. Post-it notes are always welcome in my home.

[This review was collected as part of a promotion.] I volunteer to evaluate products for 3M, and the company recently sent me a free sample of Post-it Super Sticky Notes, 4 x 4 in., Rio De Janeiro Collection, Lined. These are great--just what I needed! The colors are vivid, happy shades of orange, yellow, green, pink, and blue. The size allows me to write a larger amount of text, and the lines help keep it reasonably neat. The notes stick to every surface I tested: painted walls and cabinets, wood, paper of various textures (including heavy art papers), plastic, glass, vinyl sheet protectors, and the textured surface of my refrigerator. I'm impressed! My "test" notes stayed on the fridge door for a week without losing their grip, so now I can leave messages for my family on the fridge without wondering whether the note will still be there in a couple hours. I am most pleased that these notes will stick to heavy, textured art papers. I am able to easily make identification and process notes and stick them to the back of my paintings until I have time to enter the notes in my inventory records. Nice.

[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.

[This review was collected as part of a promotion.] Review #2 Overall Rating 5 Stars I received the product free from 3M. I really like the large size. It can be easily found on a messy desk and I can write more information on it. The lined post-it is great. I can stay on the line and write straight on this posit-it note.

[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.] 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.

[This review was collected as part of a promotion.] I received a free sample of this, and I will definitely be purchasing more when I run out. I love everything about these notes. The size is great for leaving notes around the house, for myself and the family. The bright colors definitely catch the eye. I also use them as my daily To Do list, keeping a master list in a notebook and adding only today's tasks on a lined Post-it Note on the cover. It's the perfect size. I know if I added more items than would fit on the note I'd never get them all done in a day. Since their Super Sticky, I can move the notes around if I need to as well and take them on errands. I always have these in my office and at home.
