5 out of 5 starsI asked for a custom design and it exceeded my expectations. I’m so obsessed with it and it will go perfectly in my son’s monsters inc room!

5 out of 5 starsThe Tonie arrived quickly. There is a small damaged area and a detachable piece that will not release as intended, but the seller has been responsive and waiting to receive the replacement piece that was referenced. Communication has been polite and prompt. I will update once the replacement part is received.

4 out of 5 starsArrived quickly and safely. I was a teensy bit disappointed that the widths I ordered weren't marked on the guides as seen in the photos...but I can deal with that. Thank you!
