4PCS 8x150mm Stainless Steel Round Rods Dowel Pins - Heavy Duty Shelf Support Pegs for Cabinet, Furniture & DIY Shelving - Rust-Resistant Fastening Elements for Home Organization & Storage Solutions

I purchased these for a non-typical use -- as weights in the bottom of quart ziploc bags for sous vide cooking.They seem ideal for that usage. Although nearly the width of a quart ziploc, they are just short enough to easily insert into the bag before the food. They are heavy enough to ensure the bag doesn't float (unless it has an unusually large air bubble), while orienting it vertically (for good water circulation) if there is even a small amount of air from not using a vacuum sealer. They occupy little space in the bag, and have both a good surface finish for easy cleaning, and nicely beveled ends so they don't damage the bag.
