2x2's . . .staple Or Sticky?

I'm in the staple boat too - with cinch flat stapler

I use flat nose pliers so they do not leave crimp marks on the cardboard.

I generally mostly prefer 2x2s using a Flat Clinch stapler such as Max Hd-11Flk (Black) Vaimo Stapler which overall is the most cost effective and works. I suggest however trying one pack of Supersafe brand Self Seal Flips - Assorted (this one has different sizes in one cheap pack (at littleton coin is actually good priced for some reason as many of their product seems overpriced) and giving your thoughts here on them. This would be the only one so far that might be good imo after research but wondering about how long the adhesive lasts. These are less cost effective than the 2x2 with staples as well.

Two other options I'm experimenting with are BCW Coin Snaps or Intercept 2x2 coin holders for some higher value coins and saflips which are double pocket holders where you can place a cardboard insert in one with information. The saflips also are at littleton if you cant find them. The saflips were because I had many coins I needed to pull out a few times for photos or rechecking for error or variety and was easier than using a MAX USA CORP. RZ-F staple remover for the flat clinch staples or cut them off to open and use a new 2x2 afterwards. I also keep some for sending in coins for grading even if not using them for storage. Would also like input for those that have used any of these or try them.
