These are perfect for use with my patterns. They hold the pattern and the metal board so I can use magnets to mark the rows without ruining the pattern.
I purchase these protectors frequently as they go hand and hand with the Staples heavy duty binders which I also purchase frequently. My only criticism is the Fredericksburg store is often out of inventory of the 100 quantity of the heavy duty protectors. They have the lower mil gauge which does not meet my requirements. I wish they also inventoried the 200 sheet box as I have to order it online which delays being resupplied by a day or two. I appreciate it when they are on sale so I can stock up as it is more cost effective for my business.
I purchased these to replace one I purchased in 2022. Apparently I didn’t look closely at the 1st type I purchased. I opened them this year and knew they were not what I wanted. Sheet protectors come either pre-punched with 3 holes in the protector itself. Or they come with a side strip with the 3 holes punched there. I am scrap booking (this winter’s project) family photos started during COVID. I recommend the Staples Clear Sheet protectors with the extra strip on the side otherwise you will have to punch holes in your stock paper insert.
