Very sturdy

I used these as dividers for organizing my cardstock. Worked very well. Not too thick but sturdy enough to hold papers in place.

This is not heavy duty bookbinders board … it’s very thin white card that I could have bought at spotlight for $5 Your description is not honest I can’t use this product and I’ve wasted $35 Buyer beware … it’s just very flimsy thin card

This was a good purchase, Does what it is supposed to do. It may warp a tiny bit… but it’s a lot better than some others I’ve tried.
