We simply cant thanks Bloccs enough! When our 4 year old daughter broke her arm two weeks before our family holiday in the sun we thought it was going to be ruined. She managed to get her 10 metre swimming badge (just before the fracture) but the Bloccs cover allowed her to swim and jump into the pool for several hours a day for a full week and allowed her to be the perfect mermaid in the pool, now swimming 50 metres plus!
