When in Boracay, it's great to have tattoo. You'll get the feeling of being 'in' while there. You can select from henna or glitters tattoo. It's just temporary and will wash off in 1-2 weeks.
Get a henna tattoo. They are fun and very cheap. Expect to pay around 200 pesos for a nice piece of artwork. Mine lasted about 3 weeks.
an alternative to henna tattoo...glimmer art tattoo. fancyful and cute. very cheap too. small designs go for 80Php and 100Php to 150Php for bigger designs. it's all about fun in Boracay :)
