A round base provides a good grip for easy maneuvering, and can also be used for pleasure, as it's perfect for rocking against your sweet spots, wherever they may be. If you're new to this type of toy, welcome; glass is revered by pleasure connoisseurs for many reasons, not the least being the previously mentioned hard weighty feel that's ideal for firm massage of your pleasure points, particularly the g-spot and prostate. 
Glass toys are also extremely temperature sensitive, you'll be able to feel them warm naturally to body temperature with use, but you can also amp up the heat or cool sensation by dipping your dildo into cold or warm water before use. In addition, glass is perfectly hygienic, non porous and hypoallergenic, containing no additives or irritating chemicals. To clean, just rinse with warm water and soap, use a good toy cleaner, boil for complete sterilization, or even place into the top rack of the dishwasher. You'll be able to use your lube of choice with your Icicles toy.
