Dry-Erase Planning Card Magnets by AgilePacks for Agile Planning Boards, Scrum, Kanban, Meetings, Productivity | AgilePacks Pro Kit - 40 4x6 Magnetic Planning Cards, Magnetic Cleaning Cloth and Marker

I purchased a Quartet Glass Whiteboard, Magnetic Dry Erase White Board (avail via amazon) and got these to use on that magnetic whiteboard. They do not stick (they are not magnetic enough). I am going to try and contact the company and see if they have similar ones with more magnetic-ness. However, your board may be different. So please, consider this review in context of the whiteboard I mentioned earlier.

On the plus side, these are really handy for making a physical Kanban board. On the minus side, we have not been able to fully erase any of the magnet cards after use, which means that eventually they will become unusable.

Not really sure what the warmth means but I love putting all my customers contact information and loan information on these two have all the information I need at my fingertips

These cards are perfect for our Kanban board

Perfect for my students.

Purchased these for my teachers this past year. They absolutely loved these for their versatility! We have ordered a variety of sizes depending upon how they plan to use them.By popular request, I will purchase these for the coming school year.Thank you
