Gary Yamamoto 4-inch Grub The two on the left have no Gary stamp. The two on the right have the Gary stamp. The presence or absence of the stamp likely indicates the year of manufacture. Please check the colors and quantities in the images. They were stored in a box for use on a bass boat, but are being sold to organize my tackle. I don't think they have been hooked, but please understand that they are used. Shipping will be via Yu-Packet Post Mini.
