Abstract
In this paper we have examined hyperbolicity and relative hyperbolicity of , where , is a finite free product and each is a finite group. We have used the action on the Guirardel-Levitt deformation space, to find a virtual generating set and prove quasi isometric embedding of a large class of subgroups. We have used ideas from works of Mosher-Handel and Alibegovi\'c to prove non-distortion. We have used these subgroups to prove that is thick for higher complexities. Thickness was developed by Behrstock-Dru\c{t}u-Mosher and thickness implies that the groups are non-relatively hyperbolic.
