MUSICAL INSTRUMENT SHAPED COASTERS
2015, BIF BANG POW!
Guitar, bass and drum shaped coasters. Looks like the drum one is the only practical one, but hey it's going straight to the KISS room isn't it? These seemed to be the giveaway item with a whole range of KISS products in 2017, each getting these coasters as their bonus product. Perhaps a lot of unsold coasters?
Thanks to George Navarro for the extra pics!
