Clean Click Hygienic Square 0.25l Box 1 "Won't stay closed" Chris 02 April 2015 On 2 out of the 4 of these I bought, the lids keep popping open. That could be a very messy problem if this happened in a bag as they are advertised as "100% leakproof." This happens when they are just sitting on the counter untouched. I'll be returning them for the no doubt excellent customer service from Lakeland - probably my favourite shop in the world! A note from the team Thank you for placing your review. We're sorry two of the boxes have proved faulty. Our colleagues in store will be more than happy to help when you return.
