I ordered a two pack (green and black). Both came with the insulating sleeves. I’ve already been experimenting with fruit combos using the Downloadable PDF that comes with the purchase. My favorite is strawberry and cantaloupe. These have not leaked, and they are easy to clean and assemble. My kids liked them so much that I’m about to order two more so I can keep the kids out of mine. This was a very good purchase that I’m about to make again!
