This is a Stampin' Up! PASTELS set, featuring 48 colors that are acid-free and non-toxic. The set was released in 2002 and has hardly been used. These pastels are perfect for stamping and embossing projects, and can be used with a variety of inks and pads. Very lightly used, as you can see in the photo, one of the chalks is cracked. Still perfectly usable.
