The most popular type of screwdown for trading cards on the markettoday. This new and improved version has recessed arrowhead in eachcorner so that the trading card's corners are never touched. It also has a white frost on all four sides of the card which makes the collectible card stand out better. Invented by Pro-Mold in 1993.

Strengths: Small and compact compared to traditional style four screw screwdownswhich allows for storage of many in smaller spaces particularly inmonster boxes or shoe boxes. What made the one screw screwdown popularis the fact that you get all the benefits of a four screw, as far asprotection of the trading card goes, but with only having to use onescrew instead of four.

Weaknesses: This baseball card caseitself has no real weakness but some collector's prefer not to deal with screwdown holders because they're time consuming and tedious to screwtogether many at a time, which is why they use the snap-design holdersinstead. Fits Bowman Baseball cards from 1951 and 1952
