Storage bubble for your vintage car. The bubble is powered by a small fan and inflates to form a completely enclosed structure. Keeps the vermin out from eating your upholstery and gives a small continuous air flow to eliminate condensation. I stored my '34 Bentley in it for 5years and it came out as good as it went in. Footprint is 16' by about 7'. The bubble shown in the pictures is not the one for sale but is similar. The one for sale is rolled up and ready to go.
