• Weighs 5 lbs. (I hope you're not worried about your manicure.) 
• Water-based no-voc sealer (same used for concrete countertops)
• Channels for left- and right-handed users
• Perfect for drinking coffee, tea, or the tears of your enemies. 
• Will defeat your dishwasher, microwave, and front teeth: hand-wash only, do not microwave, don't be an idiot.
