Skin feels like good quality and appears to be sealed well. This one has a mix of large and small crunchy pieces with a air dry clay or play doh type filling. I will say, the larger crunchy pieces make it hard to squish if you want it to stay in the toast form, but if you mold it into a ball and squish it that way, it's just fine. Yes, some of the pieces can be a little pokey, but it's not too bad.
EDIT: Seal busted after 7 days. Will try to fix
