new costco squishmallows

Now in-store in the seasonal holiday toy and gift section! Costco is now carrying this 10,000 piece Squishmallows sticker kit that includes a reusable mini train case, a pencil pouch, travel, journal, sticker collector album, sticker sheets, and more. The All About Squish art kits are also back in stores for the holidays, plus we spotted 4 new Costco Squishmallows last week!

Squishmallows from Costco are the BEST DEAL! You can find Squish many places but the prices at Costco are unbeatable. The selection is more limited, and timing is key…but you can save soooo much money buying your holiday Squishmallows gifts at Costco – they do come and go, and so you need to grab items while they have them…

Price Tip: We don’t see Costco Squishmallows products go on sale often, so we don’t expect there will be further cost savings on this set.

Why We Love It

This is an awesome new Costco Squishmallows mega set of squish art supplies – and we LOVE that it comes in its own adorable storage case! We think is a great art kit and travel journal option to take along for Spring Break, summer road trips or travel or just to Grandma’s house to keep the kids busy and off screens. 

The recommended age is 6+ though from the look of the kit, we think any child who is age appropriate for pens and stickers will really enjoy this kit, including adults! Just don’t give your toddler this pack in the backseat of your leased vehicle you know 😉

This Squishmallows art set weighs over 4 pounds, and comes in its own storage case. This is also a great gift for any Squishmallows fan or collector, and is a terrific value.
