Self Adhesive Dots 300pcs(150 Pair) 3/4" Diameter Sticky Back Coins Hook & Loop Self Adhesive Dots Tapes Magic Sticky Dots 20mm White, Suitable for School Classroom, Office, Home

Used for a school calendar so I could easily switch the days and months. They stick with no problem and seem strong. Perfect for what I needed them for.

Makes putting together visual boards so simple!

Depending on what you want to use these for, I'd say that they are a little too strong. I bought them to close envelopes for file folder games. My students can open them, but with lots of effort and they have torn some of the envelopes that weren't laminated. I didn't have this problem with dollar store or Velcro brand dots. Not necessarily a bad thing, but you should be informed.

My wife went through two packs of these in setting up her classroom, using 2-3 dots per small laminated letter. The next day almost everything she'd hung on the wall had detached from the wall. The dots were still stuck to the laminated sheet, but nothing was left on the eggshell-texture wall.

As an RBT I spend a lot of time making my own materials, like visual schedules and token boards and such. These Velcro dots are amazing! I really like them in sheet form versus the roll because they stay nice and flat, and they don't get all tangled. These work really well for me.
