Reusable BM Storage bags

https://m.facebook.com/story.php?story_fbid=109979884036301&id=108284507539172 Is this worth the money? Maganda sya comoared sa disposable BM storage bags kasi less plastic na ang mako-consume. Eco-friendly. Kaso yung price nya hindi budget-friendly as what they claim. 2199 for 4 storage bags plus 1 cleaning brush for free. Would you buy this?
