I saw the ScrapOnizer cases at my local scrap store. Had to have them. The cases are so light-weight, yet durable. They close and stay sealed tightly and really cut down on the amount of storage space you need. I purchased 4 to begin with. 1 for flower embelishments, 1 for clear stamps, 1 for rubber stamps so far. Highly recommend these cases.
I had a set of four double insert trays so I needed the outer cases I now can store large fabric flowers, die cuts, and stickers where I can see them, rather than in the shoe boxes where I had been storing them.
