Bubble glass is designed by adding bubbles to the glass during manufacturing for artistic appeal. At 3.5" x 3" in size, these clear handblown glass containers are perfectly sized to hold a votive candle, but don't limit their use to candles only! They are also the perfect size for serving small fruits, nuts or olives on your cheeseboard display using our reproduction breadboards, or use them to corral little things like paper clips and pushpins! Or use them as drinking glasses, for they hold 12 fluid ounces!
