If you’re a diamond painting fan, then this storage container is for you. I have these diamonds all over the place in little bags. What a pain! I seen this and knew I had to have it. These make it so simple to grab your diamonds and with the cases being clear you immediately know the colors you’re looking for. All these 30 containers in a bigger container for storage. Nice, heavier thicker plastic material is durable. Absolutely wonderful and I love it!
