Willing to DIY? Can get from Taobao, a 1450 x 1850 cm (approx.) tinting film cost less than RM30 (better quality around RM50).
Shopee also does have it.
Saw reviews, its quite easy to DIY, just that you need patient.

Getting 'no-brand' things from online is a bet, might be inferior, normal or superior quality at a good price.
I ordered mine form TaoBao, haven't stick it on yet. But reviews on the seller are mostly positive. I saw some sellers on Shopee were flood with positive reviews too.

Anyhow, based on those reviews, it can be easily stick on, also easily tear off (with intention, not auto-drop off). So, I am willing to give it a try at such price. I PM a few tinting shop online, they quoted me somewhere around RM150 - 200 for the similar size i mentioned earlier.
