This unique product aids those who have difficulty in drinking without spilling. It is particularly suitable for those who suffer from hand tremors, Parkinson’s Disease and Multiple Sclerosis amongst other conditions. The plastic insert sits inside either the mug or tumbler and restricts the wave motion of the liquid helping reduce the possibility of spills. The inserts are made from food quality plastic and are dishwasher safe. (The tumbler and ceramic mug are also dishwasher safe). The inserts can be easily removed for cleaning purposes. A stainless steel extractor for the insert is included. Colours of the ceramic mug may vary.
