Recommended by doctors for showering or bathing, Seal Tight offers a revolution in independence and flexibility to those who have a plaster cast or require a continuous dressing to be applied to a limb. The patented, non-latex seal is totally effective in keeping the affected part dry, either in the bath or the shower, and is simple to put on and take off. Needing no assistance, it can be applied or removed with one hand using the application ring. Wide options are available for those with larger limbs or heavy casts. The durable polyvinyl bag lasts between 6 to 8 weeks of daily usage with normal care. For size, measure from tip of finger/heel to top of cast and add 25mm (1').
