Square Quart Nursery Pots - 4.25" Square x 4.9" deep - by Landmark Plastics. They seem to have the science down for making cost affordable re-useable pots. The body of the pots are thin and flexible. But the thickness is enough to create unyielding wall corners. The very top and the bottom of the 'collar' of the pot is thicker which give the collar and the rest of the pot it's strength (makes it hold it's form.) VERY IMPRESSIVE. Holding two corners of the collar I can bounce a 1 lb 8 oz glass jar of Meijer Salsa in it and it holds fine. If I only hold one corner the pot also holds the Salsa fine but the pot becomes disformed as I bounce it. The pot can hole the Salsa if I wrap both my hands around the pot, but the sides do flex. So it all depends on what you are looking for.

Found these to be thinner...and at first, didn't like that, but they are flexible and seem to hold up better - not splitting like thicker plastic can. They are taller than my previous choice, but, that's a good point also - more room for the roots. I'm happy with the purchase and would recommend them - nice quantity for the price.

Pots worked for planting seeds.A little to thin to use for anything else

These are fine, but I was really hoping for a sturdy, more durable plastic pot. I potted up all my seedlings with these, but I have little confidence these pots will last more than a single season. There's better stuff out there, keep looking.

They use the word “sturdy” in the item description. I think that is a bit of a stretch. Quite flimsy compared to the pots I have from purchasing veggie plants at Steins and other nurseries. Will still get the job done if I’m careful with handling.

I really like these pots. They are sturdy enough. A plus
