As your Bloccs protector is made from Natural Rubber Latex, you should remove any sharp jewellery and be careful not to cause a puncture with your fingernails. Rough edges should be covered with tape or a stretchy bandage. The smooth, skin-tight seal should stretch easily over a dressing.

All air should be removed from the Bloccs protector before entering the water by massaging the cover upwards towards the seal to release trapped air. This can be done by gradually lowering the limb into the water so that the pressure of the water forces the air to the top of the protector.

Gently pull the seal away from the skin to remove the air before submerging, making sure no water enters the protector.
