Sandbox Collection: This has a woven brushed backing that is soft -- It has the appearance of glitter but it's just how the texture is on top. It reminds us of sand sparkling in the sun. These are very pliable and make great bags! This measures .5mm in thickness. Can be used for keyfobs, bags, peekers and so much more! This can be washed and dried on low heat. We will be adding in more colors of these as the year goes on.
