Review on Ultima Bobbin Box - 28 Plastic Bobbins Included - Efficient Bobbin Storage Box - Threaded Bobbins - Sewing Notions and Quilting Accessories (2-Pack) by Heather Shaw

Bought 2 - obviously to keep the coils and they look big, very strong. The tab on the box is also strong, but it doesn't hold the latch well and isn't flexible enough to work properly. The box had to be crushed just to secure the latch, but then good luck opening it! I could NOT open the latch with my hands/thumbs, I had to tear the tab off the latch with a flat object. The tongue is actually broken, not released from the latch. The problem isn't cheap plastic, it's poor design with inflexible locking parts that will likely need to be bent. I have to use a good rubber band to keep them closed when I leave them on!
