This is a refill of green magic slime from the Doctor Squish range: one 100 g pot on a blister card, with a bag of glitter that the card lists as included.
The card sums it up in two steps: create and squish. Your child mixes the glitter through the slime and then goes at it - pulling, kneading, stretching. The slime also works with the Doctor Squish Squishy Maker from the same range.
Be clear on what arrives: this article is the pot of slime with its glitter bag. The Squishy Maker itself is not in the pack and is sold separately. The card carries an 8+ roundel.
Useful as a refill for anyone who already owns the Squishy Maker, and fine on its own as a small gift for a child who likes playing with slime.
