Large bumps on the front, small bumps on the back for varied sensory inputEach topper measures about 2.5" long, .6" wide, and .5" thickComes with an eraser-less pencilAvailable in 3 color-coded toughness levels:
Standard - This is the softest level, recommended for mild chewers (those who do not chew through anything).
XT / Medium Firm - This is the middle level, which we call XT ("Xtra Tough"). It's firmer, but still fairly chewy, recommended for moderate chewers.
XXT / Very Firm - This is the toughest level, which we call XXT ("Xtra Xtra Tough"). It still has some “chewability” to it, but it’s fairly rigid / pretty firm. No chew tool is indestructible, but this is usually the longest lasting level for avid chewers.
