---Pack of 2 non-return straws ideal for those with limited oral strength such as the elderly and those with dysphagia, stroke, palsy, Parkinsons, ALS etc ---Two lengths of straw in pack - normal and long (7"/18cm and 10"/25cm) ---These specialist straws feature a non-return valve in the base which retains the liquid in the straw between sips, keeping it level with the top of the straw ---Also limits the ingestion of air when drinking and limits the rate of fluid flow ---Features a clip to hold the straw in place against the cup ---One-way drinking straws are not suitable for carbonated (fizzy) or thick drinks such as milkshakes ---Please note that as with all one way straws, it is normal that some liquid may be splashed after removing the straw from the user's mouth.
