Our set includes: - Dog walking bag with integrated poop bag dispenser - Matching treat bag (detachable) - Poop bag holder (so you can hang your full poop bag on the bag) - Collapsible bowl 400ml - Collapsible bottle 550ml The bags are lined with polyester on the inside, so treats don't grease through the fabric. This keeps the interior dry, even if the bag gets slightly wet. The bags are washable at 30 degrees. There is an integrated magnet on the bag's strap, so the clipped-on treat bag doesn't swing back and forth. The poop bag holder is made of flexible silicone. The bowl and the bottle are also made of silicone and equipped with a carabiner.
