Tatay Screw Top Food Container 200ml 5 "This definitely is leakproof." Mrs Pell 29 July 2019 I recently started making home-made yogurt and have been taking portions to work but all of my existing containers leaked. I bought one of these Tatay pots just to see how leak-proof it actually was and have ended up buying 5 more. I have used the pot all of last week with no problems - no liquid yogurt at the bottom of my bag. I would definitely recommend this brand and I don't think the price is unreasonable as they will last for years. Even the lady in Lakeland agreed she uses these all the time.
