The place is on the way to the airport, with lots of traffic jams to get there. But it is worth a visit.
It employs around 3000 people, mostly sculptress who make all the animals, masks, statues etc you see everywhere else in Kenya (and in the world). You can visit the camp and see them at work in very so-so conditions. Each "artist" has its number, and if you like one, you can get its work in the shop (an amazing warehouse with everything you wish for).
Prices are fixed (no bargain), it can be a bit more expensive than in other places, but the quality is guaranteed, and ebony ... is ebony.
You can pay with your credit card. They pack it for you well. I bought very fragile fine statues of masai, which arrived safely.
