i have to say I've had 2 on display for the last year or more with no issues, ive futzed with them from time to time, however, im wondering if these are in dry environments or being handled too much ? what i do every 2 months or so is use a car detailing cleaner wipe and protector for plastic/vinyl/pleather, this seems to keep all boots, body suits etc.. well cleanesed, and hydrated if you will to avoid, flaking, drying, cracking or becoming brittle, never ever ever put soap/water to the figures, always use a mix of plastic, vinyl cleaner/protector, prefferably the wipes and they can be purchased just about any retail shop fopr about $3.99 usd
