Check the listing for details. PIANO HINGE WHITE ACRYLIC PLASTIC 12" LONG (ONE PAIR) - PW12. Condition: New. Listed at 19.02 USD. Visit My eBay Store: POP DISPLAYS YOU ARE BUYING {ONE PAIR} OF WHITE ACRYLIC PLASTIC PIANO HINGE 12" LONG 1.5" x 12" 12" HINGES Have Been REDESIGNED and are the only ones with Micro Dots® for faster / easier bonding time. The low profile was designed after our industry tested and proven Flex-Fold 2™ Hinge. This gives a cleaner finished look that your customers will appreciate. As always, our Hinges are manufactured from High Strength Acrylic with the pins made from a self lubricating acrylic. The pin is locked in on one end so you DO NOT have problems with the pin working loose. MICRO DOTS ARE A HUGE BENEFIT FOR GLUE HINGES, THE GLUE FLOWS BEAUTIFULLY UNDERNEATH THE HINGE. IF YOU BUY HINGES WITHOUT MICRO DOTS YOU ARE MAKING A BIG MISTAKE. We also sell glues in our ebay store for gluing these hinges I like the weld-on #3 the best for gluing hinges
