We are a wholesaler of Havaianas. Our company name is Juju Biju and we have been in business since 2006. Our line of products include fashion accessories, personalized Havaianas(where the client can imprint their logo on Havaianas sole) and bulk sales of Havaianas. We work in partnership with the regional Havaianas office that is responsible for sales in the northeast part of Brasil. We do carry a large quantity of models and sizes. Please be aware that neither us nor any other wholesaler can provide certificate of authenticity. Havaianas forbids any other company than itself to do so. That is because they have their own distribution channels worldwide that sells for your countrys market price. Buying from us saves your company a lot because our prices are in Brazilian Currency(Real) and below from what is practiced in your market. Please let me know if you have additional questions.
