Sinan and Melike prefer full-grain vegetable-tanned leather for the uniqueness this brings to every item. They age beautifully and develop character. The full-grain leather's surface hasn't been altered at all. Because of this, it has natural markings (such as blemishes, branding, and stretch marks). However, this means it is strong and durable and has not gone through any process (alterations). Vegetable-tanning is processed using natural ingredients (such as tree bark) as opposed to chemicals, hence, leathers produced using this process are not chemical-exposed and therefore environmentally friendly. The colours of these leathers are more natural, warmer and richer and they age more beautifully.
Sinan and Melike choose only handcrafting processes and use hand-stitching. It's a slow process compared to using a machine however, hand-stitched leather items are much superior in strength and durability. The thread used in hand-stitching is stronger and the way stitches hold together makes it much less likely to break or loosen. Particularly the traditional saddle-stitching they apply provides a very strong and reliable finish; this type of stitching cannot be replicated by machine-stitching. Hand-stitching arguably provides a more aesthetic look, clearly more beautiful, natural and captures the character of the maker.
