These bags are strong and easy to open!
Bags are great! Good quality, don't rip or have holes. Love buying from a Canadian business with an excellent product.
J'adore ces sacs écologiques que nous propose Monty's bags. Ils ont une belle épaisseur, une grandeur parfaite pour récolter et sont compostables! Que demander de mieux!!! 🤩😍
Je suis littéralement en amour avec ces produits de qualités, écologiques et magnifiques!!! Je recommande à 100%!
J'ai même eu la chance d'avoir un petit cadeau que j'apprécie beaucoup!🤩😍
As a multi-pooper owner I go through a lot of bags over a year, and these do the job well, aren't plastic and available in bulk. All good things.
Good quality bags that are quite thick and don't tear. Nice to know we're not throwing out plastic anymore. Personalized note was a very nice touch and we're supporting a Canadian company.
Reordered twice now. Quick local delivery. Great bags!
I love that your bags are compostable!
We changed from Earths Own compostable bags as these were cheaper (especially with the BOGO offer) and from a local BC seller. The triple packs and dispenser are great as have to replace less often and easy to load. Only downside is the bags are slightly harder to open but this is very minor issue for a compostable bag. Will continue to use, thank you!
I have a 55 lb Shepsky and these bags work great! Very happy with the size and the service: when we received our first shipment, it included some fun extras, much appreciated! Also enjoyed the colourful tape outside the box. ;)
This is the second order and I love the bags, especially the 45 roll ones. I also love that they are environmentally friendly.
Monty’s also love your customer service is top notch.
These are the best poo-bags. Not one bit of plastic in them. I love the colour. I'm so sick of green bags claiming to be friendly for the environment. Go Cornstarch Go! I've handed these out to friends to convert them to Monty's.
These are our new favourites. Great size, very durable and even better that they are compostable.
Our sweet girl absolutely loves this mat — it gets used almost every day. The honeycomb sections are great for berries or chopped veggies. We have just purchased a second one to alternate throughout the week!
