Food Tech - any recs for small liquid containers?

[DataColour]

My DD who's in year 10, just started food tech, needs some small bottles that are leak proof to take in liquid ingredients. It's always a few teaspoons of this or a couple of tablespoons of that, so probably a few 100ml bottles. I have found some on Amazon but some reviews mention leaks etc so I'm after some personal recommendations if anybody has found any good ones?

I used these when DS was cooking, they also have larger ones. Never had any leaks.

They look good thanks!

I used various sistema pots.

Yep we didn’t use bottles, just small air tight boxes like sistema, Joseph Joseph or really any you get from a local supermarket. You can get sets of very small airtight boxes that do the job brilliantly, just from a local Sainsbury’s. The airtight seals are the key! ☺️☺️

we use little tiny screw lid round pots - https://www.johnlewis.com/sistema-to-go-dressing-dips-mini-pots-set-of-4-35ml-multi/p6034873?s_ppc=2dx92700080448106111_mixed_home_BAU&tmad=c&tmcampid=2&gad_source=1&gclid=Cj0KCQjwr9m3BhDHARIsANut04Z6K2zLxMEstoLxCmaxvGXYUCkmzTLChJKjK-zrElbDdfNo5iPPBaoaAqyaEALw_wcB&gclsrc=aw.ds

My sister bought me these when I was weaning my son and I still use them for little snacks and things now, very useful
