Clean Click Hygienic Square 0.85l Box 4 "Good with one small problem" Phuong 12 May 2014 I have gotten tired of having to pull out the silicone seal out of my, well known brand of food boxes and cleaning it each time so I thought I would try this. I put it through liquids and it didn't leak. Decided to put it through curries and it too passed except for one small problem which was their silicone seal stained. The box itself was unstained. Such a shame for what was an almost perfect box. Will it put me off buying more? No, it's something I can live with. Fix the silicone staining issue and I'll give you 5 stars! A note from the team Thanks for taking the time to write your review. I'll be happy to pass your comments on.
