Review on 🔵 BENECREAT 15G/15ML Stackable Round Plastic Containers: Organize and Store Seed Beads, Nail Art Glitters, and Diamond Drills Effortlessly with 5 Column(5 Layer/Column) Bead Storage Jars by Carrie Spencer

. I'll call her crazy because it's funny. These have been great so far. Good thread, good thickness, excellent uniformity. I've bought many over the years and had more than my share of "disasters". Those who failed did so for the following reasons. Wrong size. Even at one company I've found that some of them vary so much in diameter that screwing them down can cause cracks in the plastic as a female part expands to fit the slightly larger threaded cup below causing sudden failure . Insufficient thread length. Some of these screw caps have very short thread lengths of only a full turn and a half resulting in insufficient thread area for connection. This creates the risk of your screw-top baton bursting open somewhere in the middle, hurling bits and explosives all over the place. Wall thickness. When manufacturers make trade-offs, hopefully they do so without sacrificing utility or functionality. I believe these parts are molded from styrene, a cheap but brittle thermoplastic. The thinner the walls, the higher the likelihood of one of the above problems. They seem thick enough to be durable. The greatest advantage of styrene is its transparency. If you store small but heavy parts, resulting in insufficient thread area for connection.
