The wood fibers are saturated with urethane resin and cured under pressure at high temperature, so it feels very smooth and can't splinter or absorb lubricant. Materials are safe with no chance of splinters, chips, or termites.
The "big" part won't bother those of you who like girth. It's not huge by sex toy standards, just too big for my personal preference and comfort, especially at my age. The product description says it's 1.5" wide average, but a couple of its ridges are 1.6"-1.75"-- enough of a difference to matter to me. The tapered tip is nice, but then it gets to 1.6" wide within the first 1.25" of length (which is as far as I could get!) and 1.75" wide about halfway along its 8" length. So for me, although I appreciated its beauty and how sensual the ripply wood felt in my hand, I really need a "Treeze Junior"!
Although the size problem disappointed me, I did enjoy the sensations of the part I was able to use. It's delightfully strong, with a variety of vibrational modes. It comes in a nice, padded pouch for storage.
