We traveled to Spain and went to the markets several times. This foldable shopping bag was perfect to use there. It’s durable and large enough to use for shopping. I carried a 9 pack of pop and a few other items, with no worries that the bag would not hold up, and there was still plenty of space for more items. I love that it folds up into itself to make the perfect size to fit into a purse or a pocket. I highly recommend this Tandoler Large Foldable reusable Shopping Bag.

I haven't had this bag long nor have I attempted to carry 50 pounds in it. I still wanted to leave a review. Should my opinion change, I will update. – I purchased two of these bags to hold birthday gifts. When I unfolded, I was surprised by the quality for the price. (Purchased the lowest price option, black, at $3.99) The straps are thick and part of the back, not a separate peives sewed on. I believe this bag will be waterproof as description claims. It was very easy to refold: fold 4 times, fold a third, then fold in half and tuck in. I am buying one for my niece to keep in her car and buying one for myself.

Very happy with this purchase. The material is thick and durable, the size is great, and the handles aren’t too long.

Lightweight

Great for traveling! Folds down flat for easy packing or putting in a day pack.

The bag is alright however it didn’t quite live up to my expectations. On the plus side, it’s large and can hold a lot of groceries and I appreciate the roomy capacity and how lightweight it is when folded. The green color is nice as well.
That said, there are a few downsides. The nylon fabric is very thin and doesn't feel as durable as I hoped for something advertised to hold 50 lbs. I haven’t tested the full weight limit, but I’d be hesitant to push it too far. Also, the handles aren’t padded or reinforced so carrying heavier items gets uncomfortable quickly.
It’s great for light shopping and I like that it folds up small enough to toss in a purse or your pocket. But if you're looking for a truly heavy-duty reusable bag, this is not the one.

I bought this bag and a different model -both in green- expecting to return the one that I liked the least.
I thought this would be the one I would return, but in the end, I kept both.
This one is very large and made with a very sturdy fabric; it folds so small that you can easily fit in a pocket. The green shade is a rich dark olive.
In general, it looks better than other foldable bags, that trend to be extremely thin and flimsy.
Overall, very pleased with this purchase.

Such a useful bag. It folds really easily and is very spacious and an affordable price. It is easy to clean and good value for the price!
