This beautifully built carbon fiber patterned humidor from Jansfuren is impressive right out of the box! If you're concerned about the seal, it does has a very tight seal, especially after seasoning the wood inside. The entire interior, by the way, does appear to be made of 100% Spanish Cedar as they claim (not just used as a thin veneer over pine wood like many inexpensive humidors are). The digital hygrometer slips in and out easily with just a slight push with two thumbs. However, when placed back in its hole, the silicone-like ring around it keeps the air-tight seal I mentioned. Bottom line: You're getting your money's worth with this model, for sure! Highly recommended : )
