Arboleda is a sustainable brand that offers handmade and eco-friendly products including jewelry as stated under the case study section. The brands focus on promoting its products as "gifts" and selling them mostly at local craft fairs and markets if possible.
Besides marketing these products to local craft fairs and markets if possible, the secondary target would be women 18-24 or those who sell their own handmade goods. This could be reached through specific marketing messaging that appeals to their unique sense of community and belonging.
These are the collateral that would accompany purchases, including letterhead.
