Gillette Venus Spa Breeze razors are the first disposables with built-in shave gel bars, so there's no need to use a separate product for lather. Just add water, and get to it!
They're remarkably easy-to-use, convenient, and safe for sensitive skin. Highly recommended.
Gillette Venus Spa Breeze Disposable Razors, $6.99 for two. Available online at Drugstore.com.
