I'm sure you've seen this product in your local grocery store, Walmart, Target, and Kmart. Dryel is an at-home dry cleaning kit. The starter kit comes with a large fabric bag that you put the garments in, stain remover solution, and cleaning cloths. This is a popular item on eBay international sites. I've sold Dryel on eBay UK in the past. I actually had better luck selling the refills than the starter kits.
Here is a listing for the Dryel Starter Kit that sold for £8.75 ($12.25 USD at today's 1.4% exchange rate). This seller charged £6.99 for shipping($9.78 USD at today's 1.4% exchange rate), which is about right for the weight of the item.
Here is the purchase history on this item. You can see it is a good consistent seller and on several occasions, a buyer bought more than one at a time.
