Plastic Weigh Boats 330mL, 125 Pack Large Weighing Dishes, Lab Scale Tray | Anti-static Square Polystyrene Disposable Trays for Powder Weighing, Food Samples, Epoxy Mixing, Crafts and Pour Boats

Just like laboratory work. Great for weighing food ingredients. Heavy enough to carry powders without crumpling or folding.

I needed something very thin and flexible for lab work. This did the trick. There is static, these are plastic, so be wary of that. Great bulk item.

Bigger than I was expecting but I will find a use for them

I mix Masterblend (a hydroponic nutrient) into gallon size A and B stock solutions. The concentration I mix it at requires 302.4 grams of Masterblend, and these trays hold that amount with a bit of room to spare. The material doesn't seem sturdy enough for reuse, but they fold easily for pouring and work for what I needed.

Great plastic disposable weighing squares. light weight and holds enough product, I really got them to fill mylar bags and I like how they fold easily to pour product into bag without spilling all over the place and bypassing the zipper inside of the bag.

Exactly what you’d want. Great value.

A functional cheap and simple product which has changed my workshop space forever. Mixing epoxies or glues? No problem. Need to measure out a specific amount of a given material? No problem! My only issue is they are a little on the light side of durability. If I was working with any sort of acid or caustic, this would probably not be the best product for use.

Kids snacks and then toss. They are food safe. Mixing little paint quantities for spot painting then just toss. Mixing 2 part epoxy. And then toss. Of course, use for weighing spices and other ingredients. Then you just fold, they form a funnel and you dump them where you need the ingredients.
