Rubbish quality - expired stock?
4 tubes arrived on time. First tube I tried to use was about 50% or more solid inside. Thrown away in frustration. 2nd tube was heading in that direction but with the aid of pliers I managed to squeeze enough out from a tube to do the job I needed it for. That took about 20% of the tube contents. The third tube was almost fully solid and having tried to use the 4th tube today I realised that too was more or less solid. Can't request a return as they were all thrown away in disgust. Threw the lot away. Expired products, rubbish, by any standards. Use marzipan instead - it will do a 100% better job than this cr*p.
