Shop Disney: Disneyland Parks Personalized Leather Goods
I like it when there is themed merchandise that makes sense and is found in the proper Disneyland area. For example, in Frontierland, having leather goods goes with the theme of the area. It is something that you might buy in Frontierland as opposed to Tomorrowland. What makes it extra special is that you can have a Disneyland souvenir that you can personalize, too.
Over at the Pioneer Mercantile located near the entrance of Frontierland, you can find these fun leather accessories.
Note that the sign says "Free Engraving Available". It seems that it always depends on the Cast Member that day if they will allow nicknames or other pet names to be engraved. They will also engrave dates if you want to commemorate your visit or a special date. The character selection is limited to Mickey, Minnie, the Princesses and Frozen (of course). They have some special Diamond 60th Celebration offerings, too.
There are some non-Disney leather bands available so if you are looking for a personalized gift, this is a good option. Remember, there is no extra charge for engraving.
