Frequent Questions Answered

What kind of leather do you use?

We work exclusively with high-quality, vegetable-tanned cowhide - the same leather used for traditional belts and saddlery. It’s durable, ages beautifully, and develops a natural patina over time.

Are your pieces handmade?

Yes, every item is cut, dyed, and finished entirely by hand using traditional leatherworking techniques. No mass production - each piece is unique.

How long does it take to make and ship an order?

Most orders are made to order and ship within 3–7 business days. Custom designs may take a bit longer, but we’ll always keep you updated throughout the process.

How do I measure for a perfect fit?

For collars, belts and cuffs, measure snugly around where you’d like the piece to sit, without pulling too tight. I’ll adjust for comfort and movement during crafting. If unsure, reach out — we can help guide you.

Are your products suitable for heavy or decorative use?

Most designs are functional and sturdy enough for light to moderate play. However, please note that they are artisan accessories, not certified safety gear. Always use responsibly and communicate with your partner.

All items are shipped in plain, unbranded packaging for privacy. The return address lists only my name, not the shop’s theme.At this moment, we do not provide the gift packaging

Care instructions

Keep it dry and away from direct sunlight or heat sources. Clean gently with a soft cloth and treat occasionally with natural leather balm or conditioner to maintain flexibility and sheen.
