This bottle opener is crafted from authentic Boston Garden parquet basketball floor which was in use from 1946-1999. What makes this one different from the rest? Each panel had 4 bolt holes for the Boston Bull Gang to assemble the parquet floor from the 5' x 5' panels. We left the bolt intact for even more story. Wood features scuffs and scratches of the floor on which the Celtics won 16 of their 17 Championships. Quality nickel-plated hardware and engraved with arena name. Officially licensed by TD Garden, each bottle opener comes gift-boxed with a Certificate of Authenticity.
