It turned out so well that I decided to make some to sell in my shop
This box is made from a hard plastic, 8in x 5in pencil box and comes with FOUR plastic mesh sheets attached with a pretty ribbon. You can store countless numbers of posts and even small hoops. There's also plenty of room underneath for additional storage of small jewelry boxes and whatever else you may desire. Personally, I keep most of my gauged, stainless steel pieces in it as well.
Plastic sheets are easily removed and washable. More can be added
This listing is for the purple glitter box with pale pink mesh inserts, secured with a mauve ribbon. Ribbon has been fixed with no-fray to protect the ribbon from unraveling and to help with restringing the box when removing the earring pages.
