Whiteboard Gridding Graphic Tape, 8 Colors 12 Pack 3mm 1/8 inch x 216feet Per Roll, Self Adhesive Chart Line Tape Art Artist Tape (PET)

Exactly what Iwas looking for. Works very well, easy to start each roll and won't tear when you pull it tight to get straight lines.Multiple colors makes a way to show different designs.

Needed lines on a white board. This works perfectly.

I ordered this to create a calendar on my whiteboard. Perfect and lots left over. I great value.

Works great and is oddly satisfying to do! I went through just over half of 1 black roll for almost my whole board and loved that I could color coordinate!

Worked like a champ, left black slimy Marks on my white board when I took it down.

Good selection of thickness and color. way more length than what looks like on the pictures.

Easy to put on but leaves a film if need toTake off

Well, this is the product for you. Like any very narrow tape (this stuff is like working with mini-cassette tape back in the day, only one side is sticky), it can be a challenging to work with. But that's not its fault, and once you get the knack, you can transform a whiteboard into a great task board! I like the various colors and that you get mostly black, since that's what you'll go through most. This is PLENTY of tape for a very big board or a few smaller, 3x2ft-type whiteboards. Overall, just a very solid product for the money spent.
