Ultra Pro Screwdown Card Frames ()

These come in a few readily available configurations. I own singles, 1x3s, and this 2x3.

Pros:

• They wipe down quickly and easily, especially by hand.
• Larger ones have tabs akin to carded merchandise for hanging purposes.
• They come in some handy capacities for regular card collectors.
• the 3x3 is directly akin to a standard card sheet!
• singles are infinitely classy, especially as...
• Single-height frames can balance on acrylic display easels, yet...
• 2x3s and 3x3s CANNOT.

Cons:

• The screws can be a mite finicky, especially with larger, clear variants.
• So long as you don't over-tighten them, you can easily back them out and line up the halves of the frame again.
• The backs ARE open, but doubling up on cards will lead to damage.
• The guide squares are only a single-card deep.
• You can line them up, but the screwing process invariably misaligns them, inviting disaster.
• If you're okay with affixing cards back to back, as these are, go ahead.
• They don't seem to offer 1x6s for Sentai/Power Rangers purposes.
