For this adorable wooden keychain combo, there are several choices of how you'd like it! I have a natural birch wood option, which will leave it open to being further customized by you! Use your own stain, use paint pens or markers to make it your own! The other options include deciding whether you want a basswood (lighter wood) or sapele wood top or bottom. I really like how the dual-wood looks. Both are harder woods that will hold up to your keys and the basswood has a nice finish to it to make it as durable as the sapele. The base is just under 3 inches in height. All keychains come with a durable jump ring and keychain ring. For an additional $2 you can add a claw clasp which makes adding and taking off your camper/RV keys to your daily keyring a breeze!
