What Customers Are Saying

Verified Buyer

Beats the ones from Target

I used Popstack last night it is a better product than the ones I got from target. Popstack comes with a metal ring which holds the container together while the Target one is just silicone.

Verified Buyer

Quality -versatile

8 Great quality silicone freezer molds with lids.
Different size compartment are very versatile. Measurements are marked on inside the thick size mold for convenience and each mold has a fitted lid to store your food . These molds are durable and a very useful product. Worth the price.

Verified Buyer

No complaints

I picked these up mainly for freezing soup and meal prep portions and they have been exactly what I needed for that. The silicone is flexible enough to pop frozen cubes out without a fight, the lids seal well, and the size is practical for storing individual servings. Clean up is easy and they stack neatly in the freezer without taking over the whole shelf.
The material feels high quality and the green color makes them easy to spot. Dishwasher safe and microwave safe have both checked out fine in my experience.
The one thing I'd flag is the oven safe claim. Platinum grade silicone can technically handle high temperatures, but something about putting these particular molds in a hot oven still gives me pause. They're designed and shaped for freezing and storage, and that's clearly where they shine. I've stuck to using them for cold and microwave applications and haven't felt the need to test the oven claim. If that's important to your use case I'd do a little extra research before committing.
For freezing and meal prep though, they work great and I'd recommend them without hesitation.

Verified Buyer

Excellent high quality molds.

So I will say I was a little surprised when receiving these and seeing the advertised pics. I personally more thought they were for like making ice or things like jello but it’s advertised more as “food prep” trays. Nonetheless I am using them as I originally intended and they work great for making large ice molds. Especially like the very large one as I use it to throw in my bucket of water which has my misting fan attached to the top. Made of high quality material and lid seals nice and tight. Great quality at a great price.

FAQs

1. Will frozen food actually pop out cleanly, or will it stick?

Yes. The trays are flexible Platinum-Grade Non-Toxic Silicone, so you press up from the base and each portion releases whole, with no thawing the whole batch and no chipping at the edges. If a portion is stubborn, a few seconds of warm water on the underside loosens it right away.

2. Is PopStack safe for the oven and microwave?

Yes. The trays are oven-safe to 425°F and fully microwave-safe, and they are dishwasher-safe on the top rack. Take the lids off before using the oven.

3. What sizes come in the set, and how many portions does it make?

The set is 4 trays plus 4 matching lids, each tray a different portion size: a half-cup tray, a 1-cup tray, a 2-cup tray, and a 4-cup tray. That covers everything from sauces and baby food up to full single-meal portions, all from one system.

4. Why does PopStack cost more than a basic silicone tray?

It is built from
Platinum-Grade Non-Toxic Silicone rather than a cheaper filler-blended silicone, so it stays flexible, does not warp, and has no plastic taste or odor. One set replaces a drawer of single-use containers and moves from freezer to oven to table, and it is backed by our 90-day return policy if it is not right for you.

5. How do I store the trays when I am not using them?

They nest flat inside each other, so the full set stores in about the space of a single tray. Stack them with the lids on to keep dust out.
